Exos in a HP SFF PC

Hi!

I’ve just been reading up for the last few weeks on SFF PCs and Hard Drives (To replace my current raspberry pi with an ssd)

I’m picking up a HP SFF G5 PC to use for Plex, and was wondering if I could buy an Exos and use it without issues.

Some concerns I had were

1. Heat - Since the SFF PC only has a fan for the motherboard and PSU (AFAIK), and I live in a place where temps are high - will heat be a concern?
2. Noise - I plan to keep this near my TV in the living room, I’ve read these drives will be very noisy in a plastic NAS - but will this be unusable in a metal PC with rubber feet?
3. Power - From what I’ve read, these SFF PCs don’t have a large PSU, at max - I’d have two drives in the system. Will power be a concern?

I’m planning to get an 8 or 12 TB drive, will the 8 be quieter?

Appreciate any help and insights - thank you!
