Upgraded to Meanwell 24V 750W power supply and needed a vent on the left side, added USB connector and Ammeter just because :) The PSU's fan blows direct at this panel, so the air guide on the back helps keep the warm air heading out rather than circulating in the base.

Actually the PS fan moves so much air it's all that's needed in the Max for cooling now. I took out the stock fan on the right side panel and basically that and the slots in the bottom become the primary intake vents. Nothing in the base (RAMBo, SSR, 12V buck, PSU) gets over 35C even after hours of printing.
