The desktop I received was damaged in all 4 corners, despite the box it was delivered in being fully intact. I contacted the seller and was promised a replacement desktop in December after sending pictures. Many emails and promises to send me shipping tracking info later, it is now April and I have not received any replacement or refund. This is a very shady and untrustworthy seller.
