I thought about doing this maybe 6-7 years ago, then I checked out my "competition" on eBay. Keep in mind that most people are uneducated about computers and components; they buy on price. I could not in clear conscience even think about selling computers with Logisys, Raidmax, or Diablotek PSU-shaped objects in them, nor claim that a GT640 or HD6450 makes a machine a "gamer;" and I wasn't going to use a pirated OS or not include it. So, I built the lowest cost system using parts I'd consider using myself, and got no bids over my break-even reserve. I ended up giving it to my niece. It's had one video card upgrade, but it is still running today.
