Hello all, Sure would appreciate some insight here. I have a Thermaltake Mystic RH-D050-2SN ATX/MicroATX Desktop Case http://www.thermalrock.com/chassis/mystic/mystic.htm **Question: The pc case as per Thermaltake says that it requires "Standard ATX PSII" PSU and gives no dimensions . What in the hell is a PSII? I have been searching like crazy, but having no luck finding one or any answers for that matter. Thanks again everyone for your help. JPMac
