I ordered this for gaming, with the intention of upgrading the RAM. I went to system information to check out everything and lo and behold! They put in a Ryzen 5 3600 instead of a 3500! Would be nice if they accidentally upgraded me to a GTX 1660 as well lol.All in all a very capable computer, I use it to run MSFS 2020 on High to Medium with no hiccups.LED light does not change colors. Green is all you get, but it can be turned off via a preloaded program.
