That was me. While it would be cost prohibitive for me to prototype with real LEGO, I can beta test in a virtual space if you'd like.
Thank you!
Do you want the source files/ dimensions? I can provide those quite easily...
I can hypothetically do testing on my own if it's too much of a hassle for you.
The PCC-02.x series is going on pretty well. I have finished the frame and the following additions:
SSD mount, 3.5" mount, PCIe card support.
I will do a fan mounting system, a power button mounting system, and maybe a pump mount next. What would you like as a practical testbench feature?
