The seller was Skytech.Pro's: Computer performs well. Components test good after 30 hours of memtest. Great specs for $170. Included a mouse and keyboard which I didn't expect. Valid copy of windows already activated with no bloatware.Con's: There was a two pin jumper rattling around inside the case. Fortunately, having it missing did not seem to affect the PC's operation, so I assume someone accidentally dropped it in. I didn't take the time to contact the seller or look up the motherboard for appropriate jumper settings. There was also some minor scratching to the faceplate. Not enough to dock a star given the price point and that neither of these hindered functionality.
