The refurbisher must have struggled with the case. It was jammed on and permanently stuck. I had to bend it open and unscrew a clamp to completely remove the cover to inspect the insides. I removed the clamp and just screwed the cover back on later with a few extra case screws I had lying around. The white label 500G 3.5" hard drive was new (it tested clean) and the interior was dirt and dust free. I didn't bother with the extremely cheap mouse and keyboard - they went straight into the trashcan. This unit had a display port graphics connector, so I had to pick up a display port to DVI cable. I reformatted the hard drive (it came with Windows 10 preinstalled which I tested before erasing) and installed Linux Mint 19 from a flash drive with no issues. I'm not a gamer and don't mind the onboard Intel graphics processor. I'd replace the hard drive with a SSD if you want more performance, but for my needs, it's plenty fast. You are also going to want a USB Wireless adapter as the unit doesn't come with one, unless you have an ethernet port available.I'd recommend one of these refurbished units if you are tech savvy and don't mind spending a few extra bucks of your own to get the unit up to snuff.
