The PC came with a defective 1TB HDD. The solid state drive worked fine, so I was still able to boot up and use the PC. I contacted the seller, and was told to return the defective drive for a replacement. Luckily I can do the replacement myself, but it was still an inconvenience I shouldn't have had to deal with. Besides the hard drive issue, I am quite happy with the performance of the PC. It runs quickly, and the solid state hard drive makes it silent, and boot ups are so much faster than a system with a conventional hard drive. I was apprehensive about buying a refurbished machine, and I infact did have an issue, but still happy with my purchase and feel this system is a good value for price and performance.
