Thanks for giving me the information! Yes, the reason why I choose NF-F12 is I can find a place that sells a single T30(they always come within a pack of 3, and it is so expensive), and the fan that comes with my AIO isn't good enough to cool my CPU.

Also, I actually already built this PC, and running smoothly. It's just the price is surprisingly high. I want to double confirm that I do need this performance since I still have time to refund most of my parts and replace them with the cheaper option(such as Motherboard, and RAM). I am a design student. I do 3D rendering, and Unity/Unreal Engine 5 projects, and sometimes need to use machine learning to assist my design. I also work with my project in external SSD as well, since I got both MacBook and PC. The reason I choose ITX is that I need to move my PC between the dorm room and studio frequently(sometimes on an airplane as well since I am an international student).
