I bought this from AR System (too many sellers), and I couldn't be happier ; minor scratches on the outside, sit on 4 feet (the same cannot be said for my last renewed purchase), samsung ssd, hynix ram, and did not get really hot during memtest86 (too lazy to get the heatsink off to check the paste). Highly recommend the machine (depending on your usage of course) and seller.If you were to get this, do update the bios after installing Windows, even if the machine is strictly Linux only.
