BB, you might want to check Mouser's website for products made by Amphenol, Bourns, or DGS. The last two specialize in 5-15R solutions (5-15R's are the standard staggered 3-pin power connectors on the back of a standard PSU [sometimes called IEC 320 connectors]) On average, they'll hold up to around 15A@230v, and you can get them with screw terminals or solder lugs. I'm thinking one or two 'panel mount' style IEC320's drilled into the back of your case, with short run IEC320 cords (w/RFI filters of course) inside the case going to each PS. Now, as far as Amphenol, take a look at their 97 series. You'll want to go with one of their connectors that supports 'Size 12' pins, cause size 12's can handle ~23A a piece. If you're still running 4 PSU's, try one of the Series 97 20-15 receptacle/plug combos, should run you about $45 US w/o the cords to run from wall to receptacle, and plug to PSU's. Kinda pricey, but I personally think while being the better of the two options from a saftey standpoint, it would also be pretty cool looking to plug your comp in with a 1 1/4" wide connector with a screw lip
