I have that same case in black, overall very similar setup. I like how it looks, but if I would change one thing in my server it would be the case. It’s quite a hassle to work inside of, and for its size, only being able to hotswap 4 HDDs is very little compared to other cases you can find.
It’s not bad by any means, but you can get better
