Considering it was refurbished, the CPU works just fine no issues as of yet haven't tried to do anything until I'm able to fully utilize it. The keyboard was missing the volume knob, mouse was broken, monitor works but small, set of miniature speakers (haven't tried them out). Only satisfied getting the CPU at the price it was set for, aside from the other parts included. I'll update this review after I get the rest of the parts - if I'm able.
