Thanks everyone! Glad everyone is liking it as it was fun to build and see come to life.
I've ran some benchmarks such as Unigine Heaven and Cinebench15 with the lid up and the gold shelf in place, and the CPU never goes above 120F, but sadly the GPU was hitting 170F. Not surprised really as its a GTX 560 Ti which are known for getting really warm (also Unigine pushes your card more than the average game does). Probably going to replace it with a 1050 Ti which is plenty to run SoT and other games/tasks. And being less than half the wattage it will run a lot cooler. Future pictures will show it better, but the gold shelf actually has large holes drilled into it for breathing and the left side of the shelf doesnt go all the way to the edge (on purpose), leaving about 1/4" gap front to back which allows for good air intake.
