All new assembly and config, for once in my life I went on something other than a square box called "classic or standard" several boxes of the same order of idea exist, Jonsbo Mod5, Cougar Conquer and certainly others, but my choice is focused on Antec for the radiator duo 360 and on the inclination of the config which facilitates the emptying and therefore the maintenance. I also added an big LCD screen (23cm x6.5cm) for monitoring, the design of the box was ideal for that, it is fixed using 3D printed part
3D printing helped me a lot, I was able to place adapters on the back of the pc so that I could easily replace the storage hard drive without having to remove the distroplate.
I was also able to place 2 fans intended to bring a corridor of fresh air directly on the 2 SSDs and the chipset of the motherboard.
The CoolerMaster vertical stand has 2 openings directly on the backplate of the RTX 3090, I placed 2 small Noctua 40mm fan on its two locations which makes a direct fresh air inlet, in short, the temperature of the backplate and kept perfectly warm.
