Finally my build is done, I'm really happy with this PC, I got all the stuff I wanted into the case and temperatures are great. Thank you to the maker of the case, to
@KSliger for superior support and patience, and
@3lfk1ng for advice.
Here is imgur album;
Specs are;
Cerberus X case, Ryzen Threadripper 1950X, Enermax 240 TR4 AIO, Gigabyte X399 Designare EX mobo, 32GB DDR4 G.Skill Flare X 3200MHz, 1x WD Black 4TB, 3x Samsung 960 Evo M.2 NVMe drives, 2x Noctua 120mm Chromax fans in front of the case, Seasonic Focus Plus 850W Gold PSU, Sapphire RX Vega 64 Nitro+ graphics card.
I had to remove one of the mobo standoffs with a dremel because the motherboard did not have all the standard holes, if I would do it all over again I would go with the X399 Taichi motherboard just to save the standoff.
Everything fits perfectly, I had to use some force when I put the 3,5HDD in place with the screws and the hinge swing bracket, but it is all good now.
Going to put the chrome feet on when they arrive togheter with the cover plate on the back next to PCI-E slots, but they are small details : )
All in all, 10/10, extremely satisfied and most of all this case will last me a long time, the quality is amazing : )
