One of the worst experiences I ever had I had here.
I walked in with a PC that had something wrong with it, they spent about 30 mintues looking at it, HAD ALL THE CONNECTORS UNPLUGGED, and told me it didn't work.
I took it back home and plugged all the connections in, worked like a charm.
I'd stay away from these guys if I were you. They have scam written all over them.
