I give 4 starts because of the proprietary power supply configuration, otherwise all else is standard. Well built / engineered case with plenty of room for additions. Good BIOS settings for power and security management etc.Has PCIE x 16 slot  for adding a good video card instead of the built in one (which I got)  Really like the computer over all, worked great right out of the box. I upgraded from a very old system, and am very happy with the performance. Games look amazing.
