ok.. I have a G3 B/w motherboard 450mhz and it runs great... even without a video card... I want to build a mini Plexiglass case for it, so yeah.. Is there a way I can convert a PC ATX power supply to work with the G3 motherboard?? Switch some wires around or something.. Im not sure... Cause the G3 motherboard has a different power up signal that the PC's do... Any help appreciated
