After much waiting for parts I was able to mash the system together with some minor deviations.
For some reason I decided to go with 1/2" ID tube. I did not consider how inflexible this stuff is.
The Aluminum handles and rad bracket did not work. I could not get good or consistent bends with the equipment I have so I gave up after wasting a bunch of aluminum flat bar. The replacement is 3d printed stands that are held on by the fan screws and locate on the corner of the fan.
I have not printed a bracket for the front usb but for ease of use I may leave those cables dangling because it makes it easier to plug into them.
Retractable usb the new thing for front panel accessories? I hope so.
The peripheral UV led strip is not nearly as bright as I thought it would be, but is still able to illuminate most of the side panel, and nothing else. It is only running off of 5V usb and is probably able to handle up to 12V. I'm happy with it because I don't want it killing the zip ties and other sensitive plastics inside the case.
The rubber front panel on the Alphacool bayres is unfortunately starting to deteriorate. This must have been sitting in their warehouse for the last decade. Not sure if anyone else who has had a German car with the same problem but I had a 2003 golf where the 'soft' plastics started to go sticky like this.
Overall I feel like this turned out better than I thought it would be. With a bit more cable routing the interior will look a bit better. The system runs nice and cool, and it is quiet enough that I can hear a very quiet trickling noise coming from the Res.
That sound is actually really annoying, so I understand why the cylinder style has become so popular.
