alternative to dell

So, seeing as how it's been three years since my last machine, I'm in the market for a new one. Last time I bought one, I just said screw it and went with Dell, because I don't enjoy the process of buying parts and building my own anymore.

But looking at the Dell site, the machine I want now will run me damn near 2k. So I was wondering if you guys know of and/or use any shops for building new machines that will do a full build including OS installation, and do it well. 2k is more than a decent gaming machine should cost.

Any recommendations?
