So far everything works fine. The product came as described. It had a few small scratches here and there and the decorative front cover seems loose at one corner, but so what? This refurbished Dell Optiplex 990 is an economical solution -- I upgraded from my hideous old tower Dual Core Duo computer. So far, so good. This computer came with Windows 10 only...and that's good -- no bloatware that has to be removed.Upgraders:Be aware that the Dell power cable plugs are spaced very close together and that if you get a standard, nonadjustable 2.5 inch SS HD mounting bracket like I did (Sabrent BKHDDH), both plugs won't reach if you are trying to use a second 3.5 inch drive in the second bay. The 2.5 inch HD sits too deep, and cannot be adjusted. Try a Corsair CSSD-BRKT2. It looks adjustable, I'm waiting for mine to arrive.Also, Dell's have a blue plastic quick dismount hard drive caddy. You only get one and you'll need to find another (try Ebay) if you want to mount a second drive.
