1.0GHz P3 In A CD-ROM Drive Bay
Migraine Man writes "Similar to the PPC-based Briq, the folks at Stealth Computer have introduced an Intel-based PC that's built into a 5.25" CD-ROM-sized enclosure. It's got a 1.0GHz P3, 256M RAM, 20G HD, 10/100 eth, CD-ROM, USB, FireWire, video, and sound. At USD 995, it's reasonably priced too. You could put three of 'em on a 1U rackmount shelf, or stuff several into a mid-tower and build your own desktop cluster. A summary datasheet is here. Very cool."
Something like a VIA EPIA EM 6000, for way way less $. (eg: under half the cost). And you would have a system that is Mini-ITX Form Factor, Micro ATX Chassis Compliant. - Not a custom hard to fix type system.
The Cappucino TX-3 has had similar or even better specs for quite a while now, and its pretty similar in size:
-Intel 815 motherboard
-1.2 Ghz Intel Pentium III processor
-512MB 144-pin PC133 RAM
-30 GB internal hard drive
-Your choice of 24x CD-ROM, 8x DVD-ROM, or 8x/8x/24x/8x DVD/CD-RW combo drive
-Built-in 10/100 base-T ethernet (RJ45)
-Internal 56K V.90 modem
-Four USB ports (USB 1.1)
-Two FireWire ports (IEEE 1394)
-No operating system installed.
-All standard I/O ports built-in
-Dimensions: 6" x 5.75" x 2.25"
-Manufacturer Warranty: 1 year
Also, CappucinoPC have the Mocha P4 machine which is slightly bigger and has specs rivaling current fully loaded computers.

You can get the barebones version of this computer from caseoutlet (http://www.caseoutlet.com/NWPc/Sumi/Sumi.html) for significantly less (about $330 to be specific). it you put a via c3, which can be passively cooled, you have a ultra small, super silent puter. of course, you'd probably be better off getting one of the new via epia m mother boards and putting it in a custom case; it end up being about the same size, cost less, and offer more (usb 2.0, tv out, etc).
