not trying to muddy the waters or anything, but I have run AMD for years and never had a problem with overheating. it all depends on case and cooling used, I use an MSI AIO but they all have the same concept and work well if there is adequate airflow

as many have said, an SSD or onboard M.2's work very well, and many newer games require an SSD.

if you are going to use it as a primary drive do not skimp on space. my first build I went with only 500 GB, but I did not consider that typically.. everything saves there, such as downloads, documents the OS... so unless you like a lot of maintenance moving things around to free up space, 2 TB would be a good idea.

really, depending on how good it runs now, you could possibly get away with just an SSD/M2 and a 2060 since the GPU architecture hasnt changed
