 CPU: Lots of choices depending on need for crunch, power reqs, and price Memory: (typically) very scalable Casing: Dimensions: with two boards: 1.339?x5.117?x 5.983? (http://www.rtdusa.com/idan.htm, modular, casing for Pc/104 modules). Another modular case supplier: http://www.adaptivesystems.com/ Power consumption: Depends on the motherboard but 10 hours is possible for example with the 486 modules. Power source: Sony Lithium Ion camcorder batteries + DC-to-DC convertor to provide 5V. Data storage: 2.5? Hard drives or solid state disks (such as http://www.m-sys.com) OS options: almost anything, really. CPU: Lots of choices depending on need for crunch, power reqs, and price Memory: (typically) very scalable Casing: Dimensions: with two boards: 1.339?x5.117?x 5.983?

 CPU: 66 MHz 486-SX (AMD Elan SC410) Main Memory: 16 MB SDRAM Casing: Dimensions: 2.75" x 1.97" x 0.95" (70 x 50 x 24 mm) Volume: 5 cu.in. (84 cc) Weight: 3.3 oz (93 g) Power consumption: At idle, (Sony) NP-550 lasts 2 hours, NP-750 4 hours, NP-950 6 hours Power source: Sony camcorder batteries, for example, NP-550 or NP-750 or NP-950. Appears that no Need for a dc-dc convertor for this one. Data storage: IBM Microdrive 340Mb OS options: Boots linux for sure. Networking: The unit has Ethernet support, we need to source an ethernet to wireless bridge. Price: 1500 USD only for tiqit + network gear + casing + batteries so my guess would be close to 2kUSD. CPU: 66 MHz 486-SX (AMD Elan SC410) Main Memory: 16 MB SDRAM Casing: Dimensions: 2.75" x 1.97" x 0.95" (70 x 50 x 24 mm) Volume: 5 cu.in.

 the server modules are slightly smaller + lighter, since they dont have any graphics hardware on board. not sure what the pcmcia options are, we might have to use a usb, or rj45 to wireless ethernet adapter (adding to weight + cost + clothing designer nightmares for sure) the server modules are slightly smaller + lighter, since they dont have any graphics hardware on board. not sure what the pcmcia options are, we might have to use a usb, or rj45 to wireless ethernet adapter (adding to weight + cost + clothing designer nightmares for sure)
