Update: With the way I was able to route the tubes I was able to put a 25mm fan! Eventually I want to make a custom loop for thus but for now AIO will suffice. Now just waiting for my G-unique psu with custom length cable and c14 bracket.
Kelvin would be the best option. The Alphacool AIO block/res is too tall. A T-line would be a good choice although the XSPC pump/res will fit in front of rad there is enough gap. Also could go with a shorter GPU for a bigger res option and pump.
