PC Version. I've been switching from PC to console for COD4 and UT3 but Orange Box had to be on PC, Half Life 1 & 2 plus episodes are the best FPS ever IMHO so I stuck with my PC for it.
Mind you, given the Orange Box contains HL2, etc. I was very tempted to plump for it on PS3 but instead I lugged my HD TV up to my office and hooked up my PC for Episode 2 and Portal (I cannot tell you how amazing it looked on a HD TV with a PC resolution / speed, just wow).
Try to be reasonable... its easier than you think...
