The computer was really clean and had that new electronic device smell when I opened it. It was in such good condition that the person I got it for didn't know it wasn't brand new. Mine came with a generic mouse and keyboard combo, which I didnt expect to be included, as it wasnt listed anywhere but its cool nonetheless. What it did come with that was listed though, was the usb wifi adapter and the internal 2tb hard disk, which in my case was a 2tb Hitachi disk with 7200rpm and 64mb of cache. I'm not sure if each of these has the same type of disk, though I'm sure they're all still the size listed. The computer works great in action, and by action, I mean internet browsing, moving files like pictures and whatnot, and light gaming(things like emulators, simple-looking indie games and TF2). It does what I wanted it to do perfectly fine, and I'm happy with that. There are 4 pci slots, with 2 being x16 (for things like graphics cards) and the other 2 were x1 (for things like wifi cards or usb cards). The 8gb of ram it comes with are enough for the things its used for. I've had this for almost a month and there haven't been any problems so far, and it doesn't seem that there will be any. This was worth the money for me. Definitely would recommend to someone who's looking for a computer for browsing, some light gaming, and one that can be upgraded to suit your needs as they change.
