Take a look at Directron: http://www.directron.com/. I'm extremely pleased with the system I bought from them in January. It is a fairly high end box, with high quality components and very well put together (neat wiring with reasonable slack, etc) that cost me less than the combined OEM prices for the components.

Their store is in the 10000 block of Harwin Drive in Houston if you're close enough to go there. I'm in Seguin and didn't want to drive to Houston, so I dealt with them strictly over the net. I had no problems with them, including no hassles about returning the first machine they shipped because UPS crunched it.
