I need a desktop, but I cannot build it myself.

[euphuistical]

I know its better and cheaper, but as a law student (brag or beat? you decide) I don't have the time to learn how to put one together, actually put it together, and deal with whatever issues I would need to fix. So, with that aside, I need to know which is the best company to buy from, and what kind of stats. I don't want bleeding edge, but I don't want a cheap one, a good middle ground is what I am going for. I would guess 1k - 1.5k would be my target price, sans monitor (and I need suggestions for those as well, I think I want two LCDs, not sure on size). I am thinking it makes sense to get a Raptor drive as a boot drive, but I am not sure on the size. Should I get one that is large enough to hold all games, or does it just need to be large enough to hold windows? Going to get at least another HD for media and whatnot. I am thinking nVidia and Intel dual cores, but I am not sure on which versions.

Here are the sites I have looked at, and any opinions would be very appreciated:

Another option is to pay someone from my school's comp sci department to put it together for a $100. If this seems like a good idea I will need suggestions on specific parts (mobo and manufacturer of the video card mostly). Also, what sound cards are good? I am just going to be getting 2.1 speakers and some good head phones.
