I might want to go with something like this
if the budget could be stretched.

Keep in mind that I don't recall hearing about any of those heatsinks so I just picked a big copper one. You could probably save some money here.
Also, about the HDDs, the Raptor is for booting and photoshop scratch disk while the Cuda is for general storage.
The gfx card... *shrug* I really did not know what would be best so I just selected something somewhat familiar, same goes for RAM. Could probably save more money here as well. In fact, go with burebista's RAM. The extra 2GB would do you much good.
The PSU is probably overkill but I like having room for future expansion and when it comes to a PSU imo you don't want to push it.
I went with onboard audio as well. I guess it just keep cost down and unless you are into hardcore audio most people don't notice much of a difference.
Dunno what to say about the tuner though, I know nothing about these so I just selected the cheapest :P
Btw, if you don't get some sort of UPS I might just consider hunting you down and giving you a kick in the rear of your pants. You could go with something a bit cheaper I guess but come on, don't skimp on your power providing/safety increasing components.
Going to try for a lower budget one now. This time I will pay more attention to the price. heh
