I've got a pair of stacker 810s. There are two versions of it - look the same from the front but not so much from the back. I've got both versions though and no complaints about either of them. They're not quite up to the latest standards (e.g. cable management), but they'll do for me for as long as I can keep them going. 
I need to replace my P4 2.8 someday soonish, so what should I replace it with?
