I ordered this Lenovo M83 from Sunset Micro, and it arrived on time. Actually, what arrived was an M93p, but the specs seem identical. The computer looked almost new, and the inside was perfectly clean. The first boot came straight up (no configuring necessary). There was a COA sticker on the case, but Windows was already activated (and needed to be updated). The hard drive seemed healthy, but I replaced it with an SSD. It wasn't in the specs, but my computer came with a DVD-RW drive (yours might not). There was a USB WiFi adapter in the box, but I never planned to use it.There were a few free tools preinstalled, including a strangely-installed Google Chrome, which had to be removed and re-installed. The only odd thing was a display language setting of UK English (relatively easy to change). Anyway, I'm very happy with it, and it's well worth the price.Early last year I bought a Lenovo M92p from Sunset Micro, and it too was clean and worked fine. I mentioned "clean" because some other reviewers complained about dirty computers from other sellers.
