After some regrettable downtime associated with video cards, broken monitors, USB 1.0/2.0 problems, I am now happily back up and running, this time with 3 P815s and a brand new 2.8GHz P4, stuffed into the same shabby old case I've always had. Did I mention that I now have 3 P815s? 200 bucks off of ebay. Ching!
