Using as a media PC with stock 2GB ram. Boots fast and installed an external hard drive to store the video. For the price it is a steal. It is not going to play games or anything like that, but for browsing the internet and playing videos it works well. All my files are MP4 format, I can't attest to playing uncompressed 1080P video but assume if your hard drive is fast enough then it will be fine.I tried to upgrade ram with Crucial 2GB Single DDR3/DDR3L 1600 MT/S (PC3-12800) Unbuffered SODIMM that it says "Frequently purchased together". It got the same error as other people where it didn't work. Haven't tried to get a stick that worked yet.Also, this is my second purchase of a mini-PC. The first was a Byte3 with similar specs but 4GB ram. This performed much worse and kept overheating on me. The processor on the Byte3 is pretty slow in comparison to this one.
