Just a quick update. I have the H510 Elite case, and from reading various tech forums and watching videos on YouTube airflow is apparantly poor due to the front tempered glass panel, and is placed low on recommendation lists for noise and thermals. I myself haven't noticed any issues. I'm not overclocking apart from using the XMP profiles for the RAM, and temperatures are well within optimal range.
Only issue I have is running RDR2 with acceptable performance/running the game at all like many others. Waiting for fixes and a full guide on optimising all settings including the advanced graphical settings for my hardware before playing the game.
Everything else is great, I'm very happy with my setup.
I am considering buying an NVMe drive though as I'm convinced that my 1TB HDD used for backups and games is dying.
