Does anyone have experience with an SN41G2 system?

Just bought this shuttle XPC for my new Linux system. Installed the CPU,
memory, HD, floppy, CDRW. Plug monitor, keyboard and power. LED on the
board comes on (so there's power on the system). Press the power button,
nothing. Absolutely nothing. Is this just a dud system or is this
salvageable?

Thanks!
