I think one of my first phone calls would be to my power company to install better power to my house, the second would be to APC to get some heavy duty UPSs. I don't have the most powerful rig around (3GHz stock is my most powerful), but I'd have to say I'm pretty up there for a lot of crunching power under one roof for "general-average" computer users. (i.e. most people don't have 8 computers in their homes).  
 
this reminds me, I have to update my rigs section for my 2 newests machines, and then get them crunching on some DPAD
