Well, first, I don't know first thing about hardware. My biggest accomplishment was upgrading RAM on an old desktop from 256 MB to 512 MB. Oh, an a couple of total Windows re-installations. So it requires me to find someone locally who can help.

Second, we have one popular retailer in town that builds custom PCs, but I noticed that their prices are on average 20-25% higher than if I go to a normal retailer and buy a PC that was built already.
