Bought this to be used as a DVR for surveillance security system. Just needed a smaller box. Throw out the 500gb mechanical hard drive first thing and installed a 250 ssd. These refurbs should come standard with an ssd, no sane person would use a mechanical drive now for as an OS drive. Added 2 12tb wd purple surveillance drives and reinstalled win10 pro clean. System running clean and smooth so far recording 5 cameras. Keyboard and mouse are very cheap but I didn't need them since its a remote controlled box. Overall for $200 this is a very good deal.
