Even if I did get a shorter riser cable, I've tried every combination to try and not hit the CPU fittings. The GPU in/out ports are just too tall with the CPU fittings. The acrylic in/out was putting some pressure on the CPU fittings.
Then I can't get my fingers in to tighten up the fittings. At one point because everything was all extended, I was up to 11 rotary offset fittings because the graphics card pushing everything up. This is what has been taking me so long trying every combination. Even bending the pipes would have been too tight for the angles they were pushed off from. They would be all weird S shape wiggles trying to get past it all the tight areas.
The GPU in/out ports at the top of the acrylic was inline with the top of the CPU block.
With it setup now for the graphics card horizontally, I'm down to 4 offset 14mm rotaries.
What I think I am going to do is make a thicker aluminium frame for the glass side panel so it extends the glass panel. Then I wont need a new side panel.
