Hey guys, a friend of mine is asking me to build him a new PC, I'm more than happy to do so, but I've not specced/built a pc for 18 months so I'm a bit behind on whats what really! 
Main spec, needs to be a normal sized black tower, 300+gb HDD, dvd-rw, wireless black keyboard/mouse, windows vista home premium (Whichever is better, 32 or 64, to be bought within this bundle).
Basically the budget is £500, he has no intention of spending it all if not needed, it'll be for windows/multimedia/internet usage, some games like football manager etc.. but nothing TOO grpahically intensive, as instead of putting down a large sum on a graphics card and worry about upgrading again soon, he's going to cut back and get an XBOX 360 for his more graphical gaming.
The only optional on this is a monitor, ideally a 19/20" Widescreen, if funds permit. Not really asking for anything earth shattering, just something quiet-ish, efficient, and that will do whats needed
Any ideas folks?
