Its a used computer from ebay, the seller is very cooperative, the package came with two big wholes on the front of the box and the back, so dont know if it was used as handles, or tampered with, the HDD wasnt plugged in right so i put it in properli because it wasnt showing, i re seated all the RAM already, memtest passed, it has watercooling in it if that helps. Advice is much appreciated.
