I really wanted to love this little machine and give it 5 stars but the fan noise drives me crazy. Just playing simple FB games makes the fans kick in as it comes on..goes off..comes on..goes off...in that pattern consistently. If you are doing basic stuff it is quiet. Even running a screensaver causes the fans to go off..I added 32 GB of ram and a 1TB Samsung M.2 NVMe. This is a pretty speedy machine. One other issue I had was when I tried to activate windows it said the key could not be found which was annoying and would not let me activate. I used the u drive included to load windows 10 on the new drive thought that may have been the issue for activation so I put the original drive back in booted..went to activate and got the same "can not activate windows Key missing" There does not seem to be any info on these machines as far as the specs and such or motherboard layout..nothing..
