If you want some honest feedback on the looks:
The only thing i would change is the colour. You already have red cables and can make the fans red using the clip on surrounds, the RIVE board has red on it also.
If you were to change the fluid to plain (clear) and the tubing to red transparent then i think that would be the cherry on the cake for this build.
But then again, how long are you going to look at it? Clock the danglies off of it and bench, bench, bench.
It is not that easy to look at anyway, the side panels are held on by loads of screws lol.
One of the few downsides to using Little Devil cases.
