Pros and Cons of PCIe NVMe M.2 HAT vs BASE

[Jiryn]

Didn't realize when bought that when I was buying parts at Micro Center I grabbed an M.2 BASE instead of a a hat.

I'll be installing either a Crucial 2TB or 4TB NVMe M.2 4x4 SSD into the system

So what are the PROs and CONS of both HATS and BASES
I know these HDs can run quite hot and worried as a base it might not cool correctly.
I see as a top it can have active cooling.

Also, trying to find a good case solution.
I have two cases, the Official Black, and an Aluminum which doesn't support either.
