Very nice mini PC, I bought to be used as an IT home lab, installed ESXi on it and it worked.Keyboard and mouse are not very fancy but are functional.I was fortunate to receive a unit with the onboard wireless/Bluetooth and little antena, although the description said it would come with a USB wifi dongle (much better this way). I also received a DVI to HDMI adapter I was not expecting, very nice.There is one annoying thing about this particular model, which seems to be common with all units - the CPU fan is not loud but produces a constant buzz while the PC is on. Enough to be noticeable while working on it. That’s why 4 stars instead of 5.About the seller -I was impressed with how neat the seller packaged everything inside the box. Super well padded. I opened the machine to check if the wifi board was present and could notice they indeed clean it inside. I don’t usually write reviews but the attention to detail and care from the vendor was such that I though it was important to leave a comment, especially when buying a used product.
