cf-668 holds flex-atx boards!

I was right...the cf-668 is a flex-atx sized case.
The site selling is refers to it as AMS gITX with XBLADE although this is a CF-668 Chyang Fun Mini-ITX Case (Flex-ATX compatible) Shuttle is supposed ship a nforce2 board in the small form factor with two onboard nics...I look at these little boxes as great single purpose web tools. Dual NICS allows you to route packets. Also see the Tyan Tomcat i845GL (S2098), which if I had to buy a flex ATX board for this type of application would be my number one choice. I've seen this board as low as $117, make sure you buy the S2098G2N, the other model only has one NIC.

Even though AMS only recommends the EPIA boards with the gITX, there are several other options out there. There are several K7 boards that could be fitted inside the case, one I know that fits perfectly is the SiS740 AMD FLEX-ATX Motherboard. There is also the Shuttle FB54 which is shown above and would offer a P4 option. The FB54 is based on the i845GE and will be released by Shuttle in about a month. Remember if you decide to go with a K7 or P4, the xBlade Cooling Technology should greatly increase keeping the system cool.
