Purchased this set.  Hooked computers up.  Ones cd drive would not open, tech support advised me on how to trouble shoot, could never get to work.  shortly after receiving the other one randomly quits displaying on the screens, would power up but no picture.  We request a replacement or refund for the one.  They insisted we send it back for refund.  Okay, They process it for refunding the entire order of both computers and only send one shipping label.  We finally get a box big enough to fit all the merchandise.  Ship it.  They Receive it and hit me with a $238.38 restock fee on their failed under warranty equipment.  DO NOT RECOMMEND PURCHASING FROM THIS VENDOR
