Welcome to being a seasoned computer professional. "Play" time is over...
I have more servers and "test" machines than I have workstations and a force feedback steering wheel I never took out of the box from 4 years ago...
I have a couple solo desktop machines around 3-4Ghz, but they are for video editing, and PVR type functions...
You other choice is to spend <$100 and just swap the server MB and get the cat back...
