So I am planning on building a PC inside an sl600m. I don't have anywhere to put the PC, so im planning on buying a shelf and putting it on there. My only concern is that it will be next to a wall, and hence its air intake is on the bottom, i don't know if it will have enough space for air there. I am planning on AIO water cooler (NZXT Kraken 63X), and i dont want negative pressure in my case. any suggestions? Open to other cases up to 200 USD, (with similar cooling performance).
My only idea to get better airflow is to get a shelf with a big hole in the middle of it so the PC would get air from there.
