Building a Quiet Media Room PC
mikemuch writes "ExtremeTech just come out with a new Media Center PC build-it project. This one takes advantage of Windows Media Center Edition 2005 Rollup 2 and uses a fanless graphics card, four tuners--two standard TV and two HDTV, the Creative Labs DTS-610, which lets you bypass some DRM, and a good-looking SilverStone LaScala chassis that fits in your media rack. The new system is way more versatile, and maybe more importantly, a lot quieter than any previous media PC DIY boxes. One drawback: We're still waiting for the cable and satellite companies to get it together on CableCard, so the system has to do without."

It must be so lonely.
$2,315? Sounds a little steep for me. I'd rather buy a 42-inch plasma TV.
Until they add CableCard or some similar feature to Media Center PC's, I think the appeal will be limited. On that subject, I don't see why the cable company would want me to get a cable card when they could just continue charging me to use their digital box.
Maybe I'll just read a book instead.

Why are people posting these lowbrow, "how to make a PC" posts? Aren't there geek forums on hardocp / anandtech / ars where people can parade their own PC creations? I mean what in the world is so educational and mindsharing about this posting?
It might as well just be
"build your own Dell system for $200 off in Dell Small Business"
What's the big idea?
Isn't there google for these things?
these posts only further slashdot into the realm of those mainstream wannabe geeks who think that making yet another PC puts them on the alpha stack.
gives slashdot a bad name! MODERATE THESE OUT IN THE FUTURE PLS.
Apple is supposed to roll out their Media Center Macs with everything you need, sans fifty-button remote. As an added bonus they'll look nice.
PocketPCs that can run Linux go for $100 used. How about a $1300 1.3TB RAID in one room, and a $500 cluster of 5 of those in the media room, with one dedicated to video-out for an extra $500? That sounds like a wicked, silent mediaroom PC that can also do a lot more.

Flash card HD (for example Fujitsu thin client hardware), Linux, MPlayer, MythTV, Matrox video card (no fan). These are the recipients for a complete multi purpose video/audio/media jukebox. No noise, no digital rights management shit, none what so ever - just enjoy.
What I found interesting is how they went premiere on everything but the graphics card - one of the most important parts. People complain want at least almost high resolutions on a 17" monitor, so you care to explain to me how this is going to look on a 36" TV screen (probably even bigger). Some "light gaming" with the GeForce 6600 on a screen that large isn't going to cut it, and it's a pretty freakin safe assumption that anymone who builds themself a $2,500 computer is probably a gamer.
Interesting article though, but on that point the seem to have forgot what crowd they're apealing to.
The so-called Media Center Macs won't have a TV tuner, for one thing.

OH, THAT'S INFORMATIVE?! WHERE ARE THE FUCKING FACTS? What we have here is a karma whore! Did you know that Bill Gates is SUPPOSED to roll out his own space rocket with everything you need, sans sixty-button remote in 2140? Did you know that Elvis is SUPPOSED to come back from the grave and play a tour in 2580? Did you know that Jesus is SUPPOSED to live here with us right now??!!
Anyone use something that can take various spdif inputs (optical, coax), and output a single optical? That's what my HTCP system really needs right now. Something like the Creative thingy mentioned, but with more inputs and some intelligence about what to output.

My old AMD 950MHz system is more than happy handling any media you care to throw at it. Its Hauppauge WinTV PVR capture card handles MPG conversion on the hardware, so there's really no need for a fast CPU for that. Being single core, cooling is less of an issue, and it's got a fanless graphics card that was much cheaper than $115. More like $20 (an ATI Rage 3D card with 8Mb). And what's the point of 2Gigs of RAM in a media system?
The description of "quiet" made me think "fanless", not "just as many fans as my existing system".
Pick up a fanless mini-itx board, get yourself one of the snap-on DC/DC converter kits from mini-box.com, or similar, put it in a nice box and away you go. I've made 3 of these so far and they work great, and are acceptably silent with quiet drive.
If you want to go to the next level, boot the mini ITX board off compactflash and NFS mount your media off a server in the basement. This is what I did to get around some heat issues. Works like a CHARM.
Fast enough for a great MythTV box, not sure why this is such a revelation.
..don't panic
I was at the local computerparts shop, you know the kind that has lots of all the stuff you want crammed in a closet size shop. I was looking for a fanless gfx card because I wanted to get started with a media PC myself. Anyway, they build their own fanless Microsoft media PCs with dual tuner etc. It looked nice and your choice of harddrive was the factor dertermining the noise leves. Granted it wasn't a high power machine, it was not a gamer PC.
I have always buyed bleeding edge hardware that needed a lot of cooling. But if you are willing to stay just a step behind the ultra cool, it's easy to build a very quiet machine these days.
Now the big deal(for me) is to get your gfx card and flatscreen tv to play together. Now I am happy that I have only choosen to use 60$ on a Geforce 6200 for testing. I am plugging my DVI on the pc into my HDMI port and I just can't get a resolution of 1366x768 which is the resolution of my tv, to work. of course I could just go for the S-VHS output or the analog d-sub PC port. but those won't give me 720p resolution. So I need to find a solution for this before I spend more money on that project.
I did manage to get a usable image using 1080i and running 1900x1000(or someting) which the TV then downscales with a ATI x800 card. The picture were very crisp and with that Microsoft media keybord, I could thow my PC out of my living room and just use the media pc. But for some reason the picture were more fuzzy with the 6200 card.
The case. Finding a mini-itx case that looks nice for under $150 is a bitch. You probably want some kind of storage too, be it flash or HDD based. Other than that, you list is entirely what I'm attempting to do to extend my Myth system.
-- I have fans? Wow.
you decide exactly what slashdot should be, and go make that happen-- slashcode is available for free.
I like a random spattering of weirdass topics.
I just hate roland pipsqueaks stuff....

If you have the space, it's way better to just buy $25 worth of shielded extension cables for your monitor, TV, audio, keyboard and mouse; put the computer around the corner or in the next room. I got my VGA cable for $15 (shielded), and two PS/2 cables for $5 each, then made my audio cables for a couple of dollars from good shielded wire and plugs. All 5 metres long. You can probably get this stuff cheaper if you look around.
The only disadvantage is that you have to walk to the next room to put in a CD, but this is something I don't need to do very often. Compared to the time it takes to burn a CD or even just read a CD's TOC, walking around the corner is well worth the lasting peace and quiet. Why spend hundreds of dollars extra on hardware just to cut down noise?
.. that you CAN build a fully functional media center for 2500$.
coming up next: build your own fully functional house for 1,000,000$.
I went through this same process when putting together a system for my MythTV box.
MythTV allows for your frontent (display system) to be seperate from your backend (receiver cards, storage, transcoding - commercial removal, etc.). So you can make a big, cheap, powerful, loud system to do all the heavy lifting, and make a scaled down front-end as quiet as possible.
But, if you need to put them all in one box, you should consider power/heat in all components. Here are the main points in mine:
- Athlon64 CPU. Lower power requirements in general, and Cool 'n Quiet feature to slow down the processor, make it much better than Intels.
- Large Heat Sink + Fan. A large copper Zalman HSF runs very quiet. In my system, with cool 'n quiet enabled, the fan actually turns off most of the time it's not doing heavy lifting.
- Good case, designed for quiet operation. The Antec Sonata has a fairly quiet power supply (the newer unit has the single large fan on the underside of the PSU), and a large case fan. The large fans run slower/quieter and still push a lot of air.
- Quiet HDD. I prefer Seagate Barracuda. This used to be hard to find, but now it seems most HDD manufacturers are making quiet drives with fluid bearings. The Antec case has rubber connectors where the HDD attaches to cut down on vibration noise. If you can use network file storage, using a 2.5" drive will cut down even more on power/noise/heat/vibration and size issues. (Taking it even further, some people use a flash based system, or network boot, to eliminate spinning disks completely).
- Fanless Video Card. The Nvidia FX5200 can be found fanless from many places. It supports MPEG2 acceleration in Linux (XvMC) and works well with MythTV.
Throw a Hauppage PVR-500 Dual SD tuner card in there, with a couple HD3000 cards from http://www.pchdtv.com/ and you've got a great MythTV PVR.
Computer-Based Media Centers will be common when they have 3 things:
1) Ease of Purchase. If I can order one online or in a store with everything I need, instead of in 20-30 different parts to install or solder or whatever, Joe Public will jump.
2) Ease of Use. Can't be much harder to use a TiVo.
3) Cost. It has to be cheap enough that the average person in a Western country could get it without having to agonize over the decision. So I'd say $800 is the upper limit.
That means that it'll have to be relatively limited in what it can do. Maybe it can go light on software or something.
The hum from my non-LCD tv annoys the piss out of me, and I should prefer the soothing undertones of cooling fans. Aah, 90mm of ambient goodness.
Quiet is all well and good, but if you want a *silent* HTPC, there is only one place to go: http://www.silentpcreview.com/.
Full disclosure: I write news stories for SPCR.
For example:
Ok, so there's justification for not using a high end processor (offloading most processing to other components), but then they go ahead and drop in a a $330 dual core CPU. I think the only justification to pick this CPU is for the 'geek factor'.
Lastly, after putting in a design like this why don't they go through and demonstrate that they components they chose were the right ones. How much memory does this thing consume while actually running common operations. What is the CPU usage for these same operations?
Anybody can create a media PC, but a responsible reviewer should provide the justification for their steps and the proof that what they did was the best (or not the best) decision.
Cablecard will happen as soon as the pay-per-show services (i.e. iTunes, the rumoured Google offering) gain more momentum. Tell people that they can get only their favourite shows commercial-free for $2/hour and cable companies will bend over backwards to claw people back. They know it's coming. That's why they're begging us to get their PVRs now - they're taking a gamble on locking us in, and when that fails they'll start slashing prices and adding features until we turn back to the all-you-can-eat model.
The US Army: promoting democracy through unquestioned obedience
I agree -- there's little more to this article than "here's the geekiest new computer parts and what you can do with them". The final page of the article attempts to address this -- ooooh, the system's unresponsive while recording 4 video streams? -- but the conclusions aren't terribly useful.
I'm at a loss to understand why they've spent over $200 for audio equipment. Apparently they've decided that the system absolutely must output digital audio, but the soundcard they've selected won't do that (at least under WMCE):
And from the conclusions:
So what do they do after spending $100+ on a sound card? Spend another $100 on an external device that converts analog to digital. Why? So they can say "see? it outputs digital!"?? Any advantage of using digital audio goes out the window when the computer is forced to output analog. By introducing another conversion step into the process you're making your audio sound worse, not better!
And the submitter claims this additional $100 POS lets you "bypass some DRM".... isn't that why they call it an analog hole?
Sounds like you guys are talking about the LG LRM-519 machine just released last week.
Microsoft and LG release the LG LRM-519 digital media recorder.

One drawback: We're still waiting for the cable and satellite companies to get it together on CableCard, so the system has to do without.
Why would the content providers agree to let homebrew PVR's use CableCard? One of the main reasons people build their own PVR, rather than just buying a TiVo for much less, is to have more control over the device and avoid DRM, which is precisely why digital cable/sattelite feeds are encrypted to begin with.
At 5 bucks a month, it would take 500 months to break even on this $2500 system.
Well, that's not entirely true. You'd also have to buy a 50 dollar DVD player.
Obviousally you know NOTHING about Tv's or Pc's.
Here let me put it to you in very simple terms. An 8 meg $15.00 video card will work perfectly all the way up to insane resolutions, although no HDTV sold can go up to those insane resolutions. a HTPC is not made to play Quake4 at 9000Fps at the top resolution. an HTPC is designed to play Video content, something that a $3.00 video card can do easily.
now go and lear something about computers ant tv's cince it is blindingly obvious that you know absolutely nothing about either.
There are smaller board formats than the 120mmx120mm form factor - the trick is to find an industrial automation supplier that will sell it to you. "It's Joe Bloggs from ..." or "I'm a student at ..." and the magic words "cash sale" will usually do the job. You really just have to let them know that if you have a problem you have other avenues to follow to solve it instead of burdening them with newbie hassles. You may even end up with something you had no clue existed with better specs and for a better price than the board you were originally after. A lot of these places don't bother to keep their websites up to date.
I put together a system using the Zalman TN-500 case. This thing is expensive but it is incredibly well made and would probably survive a small nuke. I needed a quiet PC for my home recording studio but didn't want to sacrifice performance. I've got a 3.2 GHz P4 with an ATI XT800 Pro GPU. I can play the latest FPS games at full speed and I don't hear a thing from the PC except a faint disk drive access at times. I'll probably try to boot from flash and run the drives in another room with a gigabit network connection. The Zalman case sucks heat from all the critical motherboard components using these gold heat pipes to these massive fins on the outside of the case. The temp of the whole thing runs in the low 30s celsius all the time.
yeah that Music Player Daemon, and a couple hundred gigs of flacs make a great home stereo box.
All These home DVR thingies still mean nothing to me.
Its just another BOX on top of the Cable Box. Most DVR from Cable Providers suck, but we put up with them. why? Well, putting aside all the drm stuff, streaming, and sharing of your recorded content, its still just another box on top of all your other stuff. My Current box allows me to record 2 DIGITAL CHANNELS while I play back a 3rd. Untill the CableCard becomes a standard, Ill stick with my leased box. By the time the 5$ something a month catches up to the almost $3000 price tag of a descent setup, CableCards will be standard issue, and then, it would make perfect logic to stop leasing and "beef" things up.

Or is it so they can play games with uber sound processing effects?
(Also, I guess, I haven't been dumb enough to buy DRM'd online music or DVD-Audio, so the $100 rip-off dongle is a non-starter for me anyway).
After that, I think those (often colorful) Antec fans with the variable speed switch are rather good and quiet.

No; it wasn't worth it to design and tool a whole new case for the only board in existence, which seems to have been mistakenly shipped to you.
In all seriousness, where did you get your board (and for how much)? I saw mini-itx claim a few are in the wild in Japan. Any luck stateside?
How do you know what they will or will not include?
I would rather want a Linux system on my HTPC/MediaCenter, than MS Windows Media Center edition.
Also, wouldnt it be enough to use an integrated graphics circuit card than an graphics card?
VIA Mini-ITX sure looks interesting for this kind of things.
I tried googling it and couldn't find anything in relation to media pc etc
Everyone at my work is very smart. Three of us decided to build ourselves MythTV boxes. Of the three, only I succeeded, and only because I had a friend who had already succeeded to help me finish the process. As things stood about six months ago, I could not recommend installing MythTV to anyone because they might simply never get it working.
It doesn't need a "skin" to fix this problem - in fact, I'd have been much happier if I'd been able to configure most of it with a text editor - it needs to rethink the fundamentals of how most things are configured.
Xenu loves you!
Why the HELL would they choose WMCE for this hardware!? Actually going to the trouble of getting past DRM just to encode it to MS proprietary format? How silly can you get?
Bought an Xbox 360, which is positioned as a media centric device, ideal for in the living room. Must admit that the design at least is okay (not brilliant), so it is not something ugly in your living room ... but those fans. Jeez, I'm still amazed by the noise the thing makes. Unbelievable and I already put back my good old revoy DVD player and I'm crossing my fingers for Apple to come up with a good solution, because the Xbox 360 ain't.
Any suggestions for a quiet projector?
