About 10 years ago i used to write control software for power stations and it was standard practice where i worked to use the main server as a development box when you were working on it.

Used to have 3 screens, all 28" joined together, was fucking awesome for playing games on.

Funny thing is though the machines had arrays for 4 processers all half a gig each and a gig of ram, seemed like an enormous spec to have, and used to cost around 50K at the time, but now you wouldnt even buy an entry level PC with that little power!
