I used my NFC S4mini for quite some time now but now this will be my main rig.

This is the final destination after shrinking my big tower into a mid tower and now into this. The only part that survived from the old system is the GPU, everything else wouldn't fit.

Not much else to say other than I'm pleased with how it turned out.

I managed to get rid of the small top-hat by using some DIY PCIe power adapters. I had to use a slim PCB to make them fit. There should be 'enough' space (< 1mm) to they don't touch the top grill, I isolated them with some tape for safety anyways.
I also had to remove the GeForce LED logo and the rest of the RGB LEDs on the GPU cooler to make it fit.

New CPU installed with "65W TDP" power limits and -0.05V on vCore put in place to make cooling a lot easier while leaving nearly no performance behind:
PTT: 88W
TDC: 60A
EDC: 90A
