Is there something that will convert an AT power supply to work on an ATX motherboard? I thought I saw something once, but I can't find it now. I want to upgrade my P5-200 to a PII-350, but the P% MB is an AT and the PII is an ATX. I really don't want to spend the $100 for a new case, but I guess I can if I have to. Thanks, Gene Dascher
