GPU coole fans draw air into their shroud, then dump heated air out top, ends and bottom of shroud. So bottom intake move draws air into case and up into GPU fans. Keep in mind in an ideal world fans have their diameter clearance in front of them for optimum airflow (120mm fan should have 120mm intake clearance) .. cases rarely give us even a 1/6th of that.I have a couple options. I'd like to keep with the Lian-Li cases which mean I may have to get a water kit for the processor because of clearance issues. With the graphics card fans aiming down, I've no idea why Lian-Li show the bottom fans blowing up straight into the downward graphics card fans. Looks like a severe flow issue there to me. I'd just have the fans the other way around & then to get some inflow, use the side fans to blow inwards.
How much air flow does the memory, mobo in general & the M.2 cards need?
Hmm, do all images have to be hosted off site?
I set my cases on open center caster bases (on 30-40mm casters) so I have 50-60mm from floor to vent (30mm caster + 3mm clearnace + 10mm base thickness +15mm case feet). Link below has images and instructions to how I make them:

Also keep in mind punched metal vent grills restrict airflow by 60-85% of what an open hole flows. Front/top designer grills are often worse.
2x 140mm vents flow about the same amount of air as 3x 120mm vents .. same with 120mm vs 140mm fans of similar design and speed.
You might find guide to how airflow works and how to optimize case airflow of interest. I wrote it up years ago to help others understand the issues our cases present.
