Got this for a dedicated laser computer. It was really clean. A few scratches to be expected. Fired it up looking great and then noticed when clicking anything it was taking so long the computer would fall asleep. Being a computer guy I checked all the usual issues. lucky I  have a retro gaming computer I built with the same specs even a Dell but mini. So after changing the memory it worked as it should. I did looked it over when I got it and did find one stick of memory not seated. Without this bad stick to them it would look like everything was working. Next the wifi dangle wouldn't connect and got really hot. Again had one from the retro and worked.They are sending me replacements. All in all clean machine and cost less than building from scratch. I'm very thankful they took great care of me!
