Asus ProArt LC420

So Asus did it again. An awesome AIO with one major design flaw. The cables not only come out of the bottom but they come out right next to one of the tubes. This design flaw limits the movement of the right tube to less than 40 degrees. Every other AIO has at least 80 degrees of movement. I sometimes wonder if Asus has any computer building experience.

It's exactly what i expected, except of course I wasn't sure how the display was set up on the block. Apparently it can't be inverted and is then only set up to display in one way. The cables being on the bottom made me want to put it in upside down so that the pump was the lowest part of the loop. even if the tubing just going below the pump for a couple of inches means that any air would eventually get pushed to the radiator above, I didn't want to have any in there at all. Otherwise it would have been 5 star if the tubing was attached at the top or if the display readout was invertible.
