Summary: The hard drive was a bit small and came with Windows 7 (which worked fine). So, I upgraded to 4TB and Installed Zorin OS 9.1 (64-bit) with no issues. The system was built primarily to run xbmc media centre and play Linux games. Works great!
Summary: The computer was shipped and delivered promptly. It was exactly as described. It works great and I am very happy with it. I like Windows 7 which is one reason I bought this and it also cam e with MS-office. It is a fast computer and the graphic card looks great when setup with DVI to a HD monitor.
Summary: I wanted a Win 7 system to replace an old Win XP box. This one worked great out of the box and even had Win Office Pro preloaded and active. The system was used so obviously your results may vary.
