Ask Slashdot: Building a Home Media Center/Small Server In a Crawlspace?
An anonymous reader writes "I've decided it's time for me to build a separate machine specifically for use as a Media Center/Small Home Server. My wife and I haven't had cable TV in years, instead relying entirely on Netflix, other streaming sites, and hard copies we've bought over the years. Having just finished ripping our entire media collection (CDs, DVDs, and even our vinyls and VHS with the help of a capture card and some sweet digital voodoo) to a couple HDDs, I'm feeling froggy. Up until now we've been using WDTV Live, and it's been pretty snazzy, but I want to upgrade to a dedicated media machine instead of piggybacking off of my office computer. It'll be a Windows based machine utilizing Plex, and it's going in the crawlspace of the house. The crawlspace in question is unfinished, but I do have a dry concrete slab down there where I can put/mount/assemble something. Cooling won't be an issue obviously, and I am keeping a close eye on hardware specs with regards to moisture. It is still a crawlspace though. What would be a good setup to to house the hardware? Priorities being to safeguard against moisture, vermin, and dirt. Modified PC Tower? Rack? Build an enclosure? Something I haven't considered?
Please assume I'm stubborn and absolutely dead-set on putting it in the crawlspace to avoid the discussion devolving into the 'best' place to put a media machine." Do you have a question to Ask Slashdot? Fire away, with details, using our submissions form.

Just build yourself an HTPC machine in an HTPC case and hook it to your TV setup. You have ZERO environmental control in a crawlspace. So something like a computer is going to suck up dust by the megaton, and have humidity issues all the time.

THANK GOD!!!

reads like
"Please assume I'm a useless inflexible idiot"
One option you may try is utilizing an Intel NUC computer in an industrial fanless chassis (something similar to this: http://www.logicsupply.com/com...). The NUC should be fine for a HTPC and the chassis is designed for usage in harsh environments.

Actually there is no need to devolve into that. We don't need to discuss which places are better as you have literally chosen one of the worst places in your house for this. You will have issues with dust. You will have issues with humidity. You will have issues with small animals. There is absolutely 0 chance you will successfully protect your machine from these issues, and the fact that you have already discounted even the discussion of it proves you not only don't really want our help, but that you won't listen to it if we give it.
All I am going to say is have fun.
Look into encapsulating the crawl space. I bought 20 mil plastic for the purpose, insulated the perimeter, and sealed all the vents. Humidity levels are now the same as inside the house, almost always cooler than the house too. The only issue I have at all is that by the middle of winter any areas that are tile feel a bit chilly over the cold ground, but not that bad. Feels really nice in the summer too which takes up more of the year here than winter.
OK, granted I know nothing about where you live, but there's those things to consider.
First, info: What kind of crawl space is it? To me, crawlspace brings to mind everything from the enclosed space under a prefab home to interior unused space (or only used for wiring) in large structures.
1) Do you know what the year-round temperatures are in the crawlspace? Depending on type, they can have a lot of variation.
2) Ventilation. If you're sticking a heater down there (which is what this is going to be) it's going to warm up a bit.
3) Insects: Some sort of metal cage to keep out insects would be highly recommended. Something along the lines of a server cage, but with mosquito sized mesh.
4) Small mammals: This is probably best handled by a medium grade wire. Chicken coop wire sort of stuff.
5) Humidity: sorry, can't think of anything, other than be careful.
6) Dust: How are you going to dust it? Or prevent it from getting dusty?
Ideas:
- First off, for keeping it safe, probably be best to have some kind of dual-mesh cage to keep it safe. Outer layer made out of chicken mesh (something like a guinea pig cage would work well too) with a mosquito mesh netting inside it. Should keep the bugs and small animals out, but you'll need to do something to protect the cables.
- As far as heat goes, I'd recommend two things: Firstly, use a fan-less cooling system. Less dust build up, fewer moving parts to break, and less maintenance. Secondly, I'd recommend using a heat sink rated for a lot more heat than you planned. More surface area to dissipate heat. Then you won't have to worry so much about the dust.

If you're OK with doing some minor renos, how about building a sunken cabinet that extends into the floor? You could seal it off from the rest of the crawlspace to keep out the vermin/moisture. And you could also build something to hang some rackmount cases from so that the front panels would be facing up. This way you could get a 1U to run your OS with Plex on it, and then have a 3U case for your NAS. Oh and probably room for a batter backup too! You'd be able to put some sort of a cover over and put carpet on it so it would be hidden. But when you need to replace a drive or upgrade your system you'd have relatively easy access. This sort of setup might make cabling easier for you as well.
If it's warm and the crawl space isn't, it will draw bugs like the dickens. Maybe research those blue light LEDs and see if they really kill arthropods as well as they claim. Then you'll have mice. If the humidity doesn't kill the machine, all the mouse urine will.
I'm a little surprised that nobody has mentioned using a decent NAS instead of a PC for your hardware already. A 4 bay NAS from QNAP or Synology would store your media and serve it up via Plex or some other DNLA server. The footprint is small enough that all of the good points about not putting expensive electronics in a crawlspace become moot. HTH
Take off every 'sig' for great justice.
I'm using a TS-119+ with a 2TB disk inside. It's sitting in my wiring closet.
It's running MythTV for my TV/UPnP server, MythWeb for programming, Mediatomb to serve photos/videos via UPnP, and mt-daapd as an iTunes Music Server. I use PS/3s for the TV front-ends, and Roku Soundbridge 500s, 1000s, and 2000s for the music players.
It's about as close to silent as you get - I think it's fanless (you can see I'm not concerned enough about noise to find out). And it uses about 6w when it's idling.
I got into NAS solutions after I figured out running my MythTV system 24x7 was like leaving a 100 watt lightbulb on all the time, even when I didn't need it. I measured my old beige-box PC with a watt meter: a continuous 95 watts. And loud fans.
The QNAP delights me. All I could ask for that it doesn't do well is transcoding. There's just not enough CPU for it. But that'll come in time with some other NAS unit, or with offloading it via scripting to a full PC or Mac, when I get around to it.
