Mine came very clean with all parts intact and no boot issues. I booted it once as it came from the factory (using the EXTREMELY slow wifi dongle provided) and registered windows. Once I had that done, I shut it down and added a couple of components.Due to reading the specs, I knew I would need additional parts for my purposes, so I ordered a cheap-y Radeon 5450 card so I could run HDMI and a wifi card for internet. I attached a picture of the mobo layout because it is worth noting that it has only one true x16 PCI Express slot. That slot is very close to the 1 PCIe x1 slot (where I put the wifi card). A double-sized video card will block that PCIe x1 slot if you are planning to use it.I've been using the computer daily for over 3 months now without any issues. It runs very quiet, boots very quickly, and has all the processing power I need for daily use plus some light image and video editing. For the price, this can't be beat.Review the specs before buying to ensure it can do what you need it to. It has no HDMI ports and the wifi dongle is essentially trash. Aside from that, this is an amazing machine and well worth the price.
