By the way
@Mcnumpty2323 your ‘case chassis on castor wheels to get better airflow and move heavy case around’ concept gave me an idea….
If I put my chassis on castors, it’ll raise it up off the floor obviously. Then, I could mount the ‘push’ fans of the bottom push/pull rad onto the bottom side of the case (ie outside the chassis on the underside of the base)
Then, inside the case, it would then only be accommodating a rad with a pull fan on it - vs a rad in push/pull as I have currently internally.
So, the net result should be: more space internally, and the rad will be able to be screwed directly into the original fan mount bracket.
