Quality control was severely lacking on my order. There was a 250GB HDD instead of a 500GB. The SSD caddy only had screws on the one side so, I'm sure it was bouncing around during shipment. There was an adhesive cover over the sides to cover up defects but that wasn't put on smoothly or evenly. But, they were kind enough to send a wireless keyboard/mouse radio still plugged in the back. So, I got that going for me.
