pros : system performance is great.****cons: This PC shuts down at random for no discernable reason. Its not overheating. It just powers off with no warning and will not reboot until you unplug the cpu for a moment then plug it back in, otherwise it will not power up! cant add more than 2 drives internally with included cabling.no way to add internal optical drive.power button on the case is hard to find in the dark, its tiny and almost flush with the case. I cant stress how annoying this is.
