Had a couple of minor problems. The USB on the front of the case worked with my Logitech wireless keyboard/mouse stick, but as soon as I plugged a USB drive into the next slot, the mouse and keyboard acted up. I eventually moved the wireless stick into one of the slots on the back and all was well.Also had trouble with the power supply. I expected to get two connectors for a video card but apparently HP changed the design and only supplied one. Had to buy Molex and other adapters to get this all working.So, minor problems. Straight out-of-the-box everything was awesome.
