This is what I've come up with, the 4090 is more there as a placeholder to get an idea as I don't think it makes much sense buying one now when the 5090/5080 is coming so I'm happy to wait on that (I also should have a bit more budget by then, just in case), are the rest of the parts good enough for this kind of pc and quality enough to last? It says there's a potential incompatibility between the CPU and motherboard, is this right? I thought they were both AM5 so would work together? I initially had the Flux Pro as the case which I believe came with 6 fans but that has disappeared seemingly from the country, will I need more fans with the Fractal? Also I heard that ideally you want positive airflow pressure in the case to minimize dust build up, is this correct? Is there anywhere I can get better price/performance? Thanks for any help in advance.
