First, this is great value for the money. I tried a couple of "new" mini PCs based on low-powered chipsets, and this, for a similar price, blows them all out on the performance front. The unit I received was in awesome condition, no scratches or anything. Looked like new. Also, super easy to open (just one screw!) so if you want to replace components inside (like the included el-cheapo SSD), it is easily doable. Oh, and it came with a USB Wifi dongle (more on that below), and a cheap wired mouse and keyboard combo, if you need those.Now, that being said, the included Wi-Fi adapter literally disintegrated in my hands when I was trying to remove it from its USB port it was already in. Not cool. But no big deal, as this unit actually has a built-in Wi-Fi and Bluetooth chip. You only need to get a cheap five bucks antenna to fix on the back and it works perfectly (and you get back an extra USB port).Another thing is the ultra-cheap chinese SSD branded "KingFast". Seems to work, but I wouldn't personally trust my data to such a drive. I replaced it with one of my own instead.But aside from these quirks, the unit itself seems to be super reliable so far, pretty silent, and gets just barely warm to the touch under heavy loads. This is an ideal little PC if you want to setup a small media box, server, or emulation PC.
