I'm building up a new puter and wanted to transfer my current MB (asus a7v133) to an IBM Aptiva E56 computer. Obviously I'll be pulling out the current MB on that puter, but wasn't sure if my asus MB will fit in this case. I also noticed that the IBM PS (200w PS i beleive) has a plug with only a single row of 6(?) little connectors, while the asus MB requires the larger plug. Will I need to buy a new PS for this config? I'm not sure what kind of case the aptiva uses, but i think it is a ATX generic. It's basically the size of my newer enlight 7237 case. Basically, I'm going through all of this b/c I want to upgrade my current MB, processor, RAM in the enlight case and am transferring these components to the old Aptiva so i can use this puter at work.
