Neo or FitPC2i
Here are the fanless systems I have used
:* Neo . The whole case is an aluminum radiator, with fins on two sides, and holes.
It died after 4 years (DC input capacitor on mobo, I guess).* FitPC2i . The aluminum case is the radiator, with no fins, no holes (except for connectors).
Very small. Still running fine after 1 year (in the dust).Both systems are silent - 0db - with solid state storage. Instead of SSD I use USB key and mmc on the FitPC2i.
Various configurations use those fanless cases, you can find some more suited to your needs

Re:Looks pretty but..
To be slightly contradictory it may in fact be an engineering idea to prevent people from stacking items on top it, for perhaps heat relating issues?
We had a fanless CPE that people were stacking other network equipment on http://www.lex.com.tw:8080/product/LIGHT.htm which cause the HDD's to fail. -

Re:Nothing beats this bad boy
You should be able to find lots of small cases on mini-itx.com
Regardless, this company's Neo series
http://www.lex.com.tw:8080/home.htm
are very small (notebook HD only, no CD or other drive bays).
IIRC, they're under $400 with motherboard, CPU, case, and PS. -
Try 0 db PC, *this* is silentBuy a real fanless like the one I bought ($380):
I have 1GHz via proc, 3 eth, 2 usb (but usb 1.1), up to 512MB RAM, and sound.
Storage: I've chosen a very silent hard disk: seagate momentus 40GB 2.5" and Linux is tuned to spin down the drive: it only runs 15s every 10mn.
No CD/floppy drive: OS install with PXE and another PC on LAN.You can have a real 0db system with LAN boot or using a compact flash for storage.
Of course network boot means another PC, noisy, but in another place ;-)Believe me, I'm currently posting on Slashdot using this system, I really apreciate deep silence.
BTW, this is old news.

Re:idiot-proof
Teenagers will not take this one. Too bland sluggish and weak for their taste. Speaking out of experience as I have one in the house and quite a few in the office (circa 20-30).
The PC on the picture is LeX. http://www.lex.com.tw/. It exists in 2 major incarnations - 533 MHz C3 and 800 MHz C3. The first is fully passive cooling, the second is fanned. Both incarnations have subvariants with 1-3 10/100 Realtek or 10/10/1000 Intel Ethernets. Video is Cyberblade with shared RAM, audio and on-board chipset is Via. There is 3", 2", CF and disk on chip connector on board. The standard disk is a 2". Can take up to 512MB 133 SDRAM using a single low profile DIMM. DC to DC convertor on board, external 12V DC power supply.
The 3 interface variety make very good firewalls and routers.
The price quoted on the website is barely just above what Lex charges for the 533 with a minimal disk or flash and minimal RAM. This means that it is running either Linux or QNX.
The systems are nice, but I would not recommend them for use in anything but a dedicated server/system or a diskless terminal.
The reasons for this are:
- Bad cooling especially on the 533. If you add a disk the heat generation in the case is nearly always above the thermal throttle threshold. This makes the machine go sluggish even with minimal use.
- The video is quite sluggish and if pushed to higher frequencies takes a lot of the system memory bandwidth.

Re:Openbrick
This seems expensive (300-400 euros).
How is the performance of the Geode CPU?
I've seen some VIA C3 boards with 3-4 Nics here.
They have a US Distributor here.
I talked to them in June; with case, motherboard w 4 RealTek nics and the fastest CPU it was $370.
Here is another one with 4 nics.
I'd be using it to run Astaro firewall, which is kind of a pig for CPU and RAM.
If you only need 1 NIC, LOTS of Mini-ITX VIA systems are available for under $200 with case, mb, CPU.
Their power consumption is supposed to be around 13watts + HD.

Lex Systems makes some nice small systems
Lex Systems makes some nice Mini-ITX systems that might be right up your alley, of you can get past the horrors of their flash-based site. I bought a Light system from them a couple months ago with a fanless C3 533, threw a CF card in and installed Bering uClibc on it. Now I have a silent linux based firewall with an internal ADSL interface with enough oomph to run a few IPSEC tunnels and do some nifty firewall tricks. Best of all, since I installed that firewall and turned off the desktop system I never used the noisiest thing in my apartment is the 3 year old harddrive in my iBook, and with Laptop-mode even that isn't spinning most of the time. Silence is golden!
I've had a fanned 800Mhz C3 Light system running as a 3 port firewall at work for over a year now and it works great. A friend of mine has several of them scattered around town as NAT/DHCP/IPSEC appliances for the different branches of the company he works for. Never had a problem with the systems, only the DSL lines their connected to.

Re:Recommended disk: Seagate Barracuda V
I just got the slower IBM/Hitachi 80 GB 2.5" (IC25N080) drive for use in a Lex Barebone, and turning it on for the first time it really freaked me out: with two desktops churning away close by, I couldn't hear anything. Even at home with no other noise source, it's barely hearable even when accessed.

Duh. Build your own
... using a Lex board with 3 ethernet ports (WLAN and MoDem optional).

Why don't you just put CAT5/6 in the walls ?My good Lord ! There we are: anno domini 2003. And where are you ? 1973 analogue multiroom..!
Dude ! :-D
What I do not undersatnd: You can have cables in the walls. And you want to lay audio cables in order to transmit analogue audio, that requires an Amp and speakers in each room ?
Why don't you replace the audio cable by CAT5 or CAT6 ? Then you can transmit ALL data on the cable (yes, even MP3) and watch video, listen audio, surf the web, play games wherever you have a network-client, evaulating this data. All you will need is some multimedia cabable thin-clients in each receiving room and a pair of active-speakers.
Maaannn... here is what I have done/do at my home:
I live in my own two room apartment, one kitchen one bath and toilet.
- I have CAT5E in the walls,
- (this is wehre my AV Receiver and selfmade MediaServer is)
- another corner, where my DSL modem, switch and HomeServer is,
Today all PC solutions have a few things in common:- IRDA, USB, AC97, TV & VGA-out and Linux. That is all you need.
This is how the MediaServer is built up:
- a system-HDD
- a swappable (not Hot, mind you) media HDD
- a DVD-Burner
- an M-Audio soundcard (want to have more than 48KHz on S/PDIF) for local sound with my 5.1 setup in the same room
- a DVB-s (that is European digital TV and radio broadcast over Sattelite) PCI card
- an analogue TV/Video card (to which my old VHS is connected and a terrestrial antenna)
- and soon an additional Matrox GH450
- all on a ATX P4 1,8GHz system with 256MB RAM
Please note, that the fastest component must be the HDD, according to how many streams you want to transmit simultaneously. The CPU could even be a VIA C3 Nehemiah (<Celeron) but I want to be able to rip CDs quickly with this system, that is why I have a P4.
This system is cabable of streeaming simultaneously (!) several media streams (MPEG2/4, MP3/Ogg, etc.) to any location in the appartment !
I did not practically test multiple asnyc streams, as I am out of money for a while ;-) But as soon I have some bucks over I am going to get the clients:
For the bedroom:- C3 based Linux-STB (Allwell.TV)This system will connect to the small bedroom TV. It has an option for dual PCI riser, that also holds an MPEG4 chip (the Sigma Designs one). Its vidoe chip is even supported by DirectFB! It has SCART-out (for the European market), but also generic TV-out and S/PDIF
For the kitchen:- LEX Thin EPIA client with MPEG2 accel, booting from DOM/DOC (or LAN) and running LinuxThis system will get a pair of active PC speakers with NXT technology (very flat). 64-128MB RAM is enough here, no HDD, instead DiskOnChip or as alternative: more RAM and LAN-boot. YMMV. As soon the LCD panels get cheap, I will add a touch-sensitive to this one, so I can have breakfast while reading
/. (oh, my)
As for the software...that still is not perfect. At the moment I have set up an icecast server and VideoLAN. This would allow for comfortbale media streaming to Windows and Linux clients, however I plan my own software, though based on these (as well as on Mozilla and DirctFB, maybe gstreamer)
To say "Multiroom" in 2003 is the same to say "Ethernet". That simple.

Re:C3...?I've got a pair of C3 boxes at home (Lex systems, see http://www.lex.com.tw/), one of which is a 533 (fanless) using a CF disk (so no moving parts - truely noiseless).
I've only had them for about 4 months however they've been more reliable than the Celeron I bought at the same time.
Just replaced that (dead) Celeron with a 1 GHz C3 and so far it's solid as a rock.

Re:why I'd like one of these in my car
There you go!
Mother of all small Motherboards
Built-in CF slot (CF is cheap and much more reliable than HDD in the car).
+12V power (no need for power supply!)
USB, ethernet, video, audio, you name it.

Re:Noise ? Wireless ?Lex Barebone has fan-less 533 MHz Mini-IXT boards, including one with three Realtek 10/100 chips, or two Intel 10/100 and one Intel GigE.
There's also a Atmel-based 802.11b controller you can add as an option. Can't seem to find it on their site, but I've seen it at some European resellers.
Not too expesive either: with the wireless option and the Intel chips, it runs at around 400 EUR (plus memory and storage).

Re:Computational brick
No Hard Drive is going to stand up to a offroad racing truck. Use a RAM-based rocketdrive, or a series of 1GB Solid State CF drives. Lexsells an Via based Book that fills your needs pretty well, except that it doesn't come anywhere near 2Ghz. But it does run off of 60w, 12v that it could pull directly from the vehicle. It also runs remarkably cool, has hard disk slots (Bad idea) and a CF slot, 1-3 ethernet ports and 2 firewire ports, and upto 512MB Ram. Clamp a 120mm fan (with filter) to the back, and it should have no trouble running through Death Valley.
The better question is, of course, what are you going to do that you think you need a chip that draws 69W of power? Applying photoshop filters to live streaming video of your races, to be sent out over software firewire 802.11g adapters? Generate 3D maps on the fly from bumper-mounted webcams and compare that to existing topological maps to ascertain position?
What's the secret, Animats? -

Re:Agreed 1000%
Try this if you need dual ethernet, it has 3 in pretty much the same form factor and a CF slot! http://www.lex.com.tw/cv860a.htm

An alternative
This case + a mini-itx motherboard (available on same site), a slim CD-rom, a 2.5" HDD and an extra ethernet card in the available PCI slot. Tada! A VIA EPIA 5000 would make it fanless and very quiet (except for the harddrive then...). 11.50"(295mm) x 2.50"(63.5mm) x 10.75"(273mm).
And then there's the 42(H) x 220(W) x 165(D) mm LIGHT System that you can get with three ethernet ports. Though I donät know where to buy it yet.. -
Bah! This is what you need for a diskless firewallLex LIGHT barebones system
Lex Systems
Its tiny, powerfull, and has tripple ethernet... what more could you ask for?well maybe a fanless cpu.
