Well I'm going to retire a few this week, can't afford the electric to keep them all going. Thinking of selling the two HP boxes and maybe also one, maybe both of the core 2 duo boxes. Then with the money raised see what I can replace them with that is more power efficient and see how close I can get to the output of those 3 or 4 boxes with 1 box that uses a fraction of the power. That Athlon X4 640 pulls about the same power as one of those HP X2 4000+ boxes does, yet has faster clock speeds, a little better architecture, and 2 more cores. Pretty cool... so who knows I may replace the 4 dual cores with a couple quads and call it a day. Will compare cost/output of an i7 and an AMD hexas too.


As far as the nicest in the cardboard, well, you try and find a case for that weird motherboard
