I was a bit disappointed at first as the picture showed USB3 ports and Display port video, so I bought adapter cables as my monitors are not display port. The PC had USB2 and DVI video. It seemed slow to boot and to load things. I added a USB3 card which is working well, and the DVI is no problem. I cloned the drive to a 240 GB SSD and it is fast and quick now. I secured the SSD to a 3TB HDD for storage and mounted it in the PC. There was a third SATA socket on the MB and I used a splitter on the power cord for the DVD drive. The computer is fast and very quiet. Everything works fine and the specs never claimed USB3, just the picture. This is a great value and I have recommended these or others from this seller to friends and family.
