Received that computer on a Friday.  Didn't see any obvious issues on first inspection but things changed when I powered it up.  It kept displaying a message about a hardware jumper removed to reset some system password.  Called the tech support number twice but couldn't get an answer.  Eventually figured out where the jumper was located and resolved the first problem.  Next, it would stop on startup and ask for a keystroke to proceed or go into setup or diagnostics.  Removed the CMOS battery and found that it was completely dead,  Replacing the battery remedied the problems after a couple of startups.  Never did hear back from tech support after leaving a voice message.  Maybe they don't speak english.  I'm somewhat computer savvy and managed to work my way through this.  Someone who wasn't would be pretty much screwed.  Once I had it running and looked it over, I found that they had not masked off the areas where the LED indicators would shine through the front panel, so the only indicators you have are the light on the optical drive and the sound of the drive and fan.  One of the worst refurb jobs I've ever seen.  Had to vent here since it looks like I'll never hear from their alleged tech support.
