Air flow and case choice - Phanteks Enthoo Pro M or P400S

[drumphan73]

mATX mobo with Intel Core i5 6500 with stock fan cooler, no OC, geForce gtx 1060 gpu, 8G RAM, nothing special. Should I really be that concerned about not having enough air flow/intake?

The P400S has a baffled front cover with only gaps at the top and bottom for intake whereas the Enthoo Pro M has mesh front for fans.

I'm leaning toward the P400S, but that closed off front panel is my sticking point.

I use the p400 just fine.
To add I'm not even using SP specific fans, as the ML aren't SP, they're more middle ground. That and through a radiator and I'm still quite alright all around.

Check temps in my PCPartPicker build to confirm loads with my parts.

Both are fantastic cases, I'd get the Pro M though, has more functionality imo and is smaller.
After you build your first PC, you look at your case and you want more, whether it be smaller or more functional.
The Pro M also has a Tempered Glass version for a premium.
