This is my old desktop and it's working and very reliable; I just had to do repairs for my new rig recently and got a pure sine wave UPS that was ridiculously expensive and I can't really justify having this one around anymore. It has my old accounts in it now and I plan to system restore it. I'm not sure if it'll automatically install Windows order 10, but it probably will. As for performance, I think it could be an amazing rig to run older games. I was able to boot up Dark Souls 3 and it was running at around 20-30 fps. I'm going to test it once more before I wipe it. PS: I don't think it has the original graphics card. I think this one might be actually better than the original (4850?). I just don't know how to price it accordingly so I'll have it trickle down in price overtime.
