Soldato
I went pretty much the same as JayGee but I also have one in another build that's in a 5-1/4” bay...when those were still a thing.
I split mine - because I seem to like making life difficult for myself:
Split Aquaero
Not sure I'd recommend it as it does seem to make the buttons a bit unreliable - the rest works fine though and it's an unusual way of doing it. It you have the space - I didn't as there are pumps in the way - you could mount the whole unit this way without splitting it.
