1. I’ll start off with the tubing. I listed it as a pro for the build quality of this unit, but this thing has some heavy duty tubing. I’m not sure on the diameter of it, but it’s also stiff which made routing it around in my 90 degree flipped case (Silverstone FT02) quite a pain. I eventually managed, but it took some tweaking. 2.
