I bought 3 of these desktop pcs for my office and 2 of the 3 were shipped upside down in the box and I know maybe that wasnt in their control and maybe the problem with the shipping company but they finally came and when we went to put them in one of the latches were jammed and the pc wouldnt open we had to pry it open and on the second one the fan is making rattling noise and all the CMOS batteries are bad also a part of the back face plate was missing
