I am not a gamer & haven't needed tech support, so will not rate those areas. I started by connecting my old LCD monitor &  pairing my wireless keyboard & mouse (instantly). I then partitioned the drive & installed Linux Mint on the new partition. I then restored the backup from my 8 year old PC. I had no setup problems & the improvement was immediately obvious.The first couple of days, one of the cooling fans would occasionally kick into overdrive with a grinding/grating noise, but I decided it was just needing to "break in". By the 3rd day, it was no longer happening & it has been quiet ever since.My old PC had 4GB Ram & was frequently freezing when I loaded more than 3 tabs on Firefox. With 8 GB, I have had no freezes on this one. The only minor complaint I have is that my Anker bluetooth speaker drops out one room closer than it did with the old PC.Overall, VERY happy.
