There's a table for the v6 GPU compatibility and it says the 2080 Super Strix is compatible with notes of 'Recessed power connectors'. Assume that means some sort of low profile connectors into the graphics card that would otherwise prevent you from putting the side on the case?
I'm probably going to have a bit of a toy around with my build before I finalise it with fans. Long term, I'm waiting on slim 140mm Noctua Chromax fans (not even announced yet... could be a while) that I plan to put on either side of the C14S - I think this configuration should allow me to keep the power supply in the standard position. Going to also try mounting the PSU to the front - someone managed to put a slim 120mm fan in the gap between the motherboard tray and front of the case, which looks interesting.
