This barebones system is a great deal. Installed a HD with no issues. Loaded Windows 7 and drivers via external USB DVD ROM without issue. Ran Windows Experience Index, processor scored a 7.3, RAM scored a 7.3, Graphics 5.1, Gaming Graphics 6.5. RAM is a 1 8GB stick which leaves a slot free to add more if needed. Also has VGA, DVI and HDMI video connections.
I did not like the way the wiring was ran from the power supply. Might have to rerun it if I decide to add an internal DVD drive. Also, the power supply does not have a kill switch. The main power button is too well hidden - might be hard to find for some people, others may like this.
Overall, I am very pleased with this system. From unboxing to OS running took little over an hour.
