My wife and I don't do gaming. had no need to contact tech support, and never use sleep mode, so I am unable to rate those above three features.  This desktop computer comes in a small, slightly crowded case, and delivers speedy performance with lots of memory at a very reasonable price.  This last feature is important to me because I always try to buy the largest amount of RAM that I can afford.  In summary, this is a budget desktop that delivers excellent value in my opinion.
