The best option if you don't want to build is to go to a local PC specialist. Ask them, if you buy the parts, will you build it for me. They say yes, you hand over around $100 (never checked, but I think its around that for my local shop) and the parts, come back a while later and take home a PC for a fraction of the price of alienware. Or you could build it your self with help on what to do here if you get stuck.
