It's one big, dual dual channel (or something) eight slot board, so yeah it's limited to this iWill board, or perhaps the chipset. It's got 4GB in it supposedly but only 3.5GB are seen even in the BIOS. I'm beginning to think this is because the CPU and platform can't do 64bit instructions so the CPU can't address all the RAM regardless of what OS is installed.
I think it's a standard EATX case and motherboard. The front panel header is non standard pin out but if your case has separate pwr, rst, HDD/msg LEDs then you could set it up fine.
I am not sure if the ATX connector is standard or not and im not going to try it out!
£10 for a ss7 board and a GeForce Quantum Fireball (whatever the hell that is) is a great buy, enjoy! Standard ATX connector and a cr2032 aswell
