Could not even turn on.as CPU blew circuit breaker when I plugged it in. I wanted seller to just replace CPU but seller wants me to return every thing. LOTS OF STUFF. two 24" monitors, CPU, keyboard, mouse, cords etc. All I wanted them to do is replace CPU with one that won't trip the breaker. I only have one RMA so I guess I'll have to find a BIG box to put it all in.Hank  365.
