I would consider doing so (building a PC), you'll save a ton of cash.
Or, resort to a site like
http://www.buy-abs.com <-- customer service is excellent if you need it.
http://www.ibuypower.com <-- I ordered a prebuilt from them once a while ago. Ordered 3 day shipping and got it in 3 days. No problems whatsoever. VERY BIG HINT though: Choose a quality power supply. The only good ones that I see listed is the Enermax SLI ready PSU (and maybe a few others, just skimmed through this really quickly).They do have watercooled systems if you need the quietness. Be prepared to do some research on selecting your parts (they don't offer a whole lot of selections, but hey, it's prebuilt). Another hint: Call the guys on the phone and place your order by phone. These guys will give you personal advice (but do your research before buying, as always), I know I did and they told me to get a quality power supply to power up my rig.
If I were you, this is the system I'd be looking at (overpriced, but for a beginner, I guess prebuilt might be an easier option).

Do plenty of research. Especially on your motherboard (hint: see sig).
Of the motherboards that they list, the only good one is the eVGA (it just came out, it might be buggy though) and the Gigabyte GA-K8NXP-SLI (might be unstable, but if you add some cooling you'll have better luck).
Good luck. You've got PM.

Not too shabby considering that they build it for you. You could save a little bit of money by building it yourself though.
Edit: "Wireless Network Adapter ( [Special !!!] Wireless 802.11g 54Mbps PCI Adapter ) "
^-- Get rid of that. I guess I overlooked that and forgot to hit "None." The board comes with a wireless adapter anyways.
