Question Need a decent-good airflow ATX case under ~100$

[Dddsasul]

So first of all, the things I am planning to put inside are:

• ASUS TUF GAMING X670E PLUS WIFI
• AMD Ryzen 9 7900
• Noctua NH-D15
• Gigabyte RTX 3070

I have no idea about how to pick cases and I don't want to buy some 20$ trash and call it a day.
I need at least 3 USBs on the front pannel (which is what causes me a lot of problems, my current case has 4 and I can't find good cases with 4 USBs anymore)

So far I was considering:

• Thermaltake V200
• Aerocool Cylon
• Montech AIR X

Looks are not hugely important, as long as there's a transparent side panel I'm happy. I don't care if it has RGB or not, I don't care if it's white or black (I would stay away from pink though).
Worst case scenario, I am willing to drop down to 2 front panel USBs but any less than that would be a major inconvenience.
This is my second time building a PC so I would also appreciate tips on how to tell which cases are good since I have no idea; what makes airflow good?

In no particular order, though I'm partial to the Lancool 216:

SilverStone FARA R1 V2
Fractal Design Pop Air
Corsair 4000D Airflow
Cooler Master Masterbox Q500L
Lian-li Lancool 216
Antec DF700 Flux

Montech isn't bad per se, but they generally use lower quality materials and sometimes have rigidity issues. There's no denying they're pretty much the best budget case maker though and if you were looking at them I'd suggest the Montech AIR 903 MAX.

Exceptionally well built. Outstanding Air-Flow. HDD Capable. And most importantly aordable is the timeless Lian Li PC-7HX. I'm currently using one for my own build 9 years now and still kicking. Not to mention I recently upgraded my CPU Cooler the the Noctua NH-DI5 which fits perfectly. You might be able to find one used and in great condition on eBay or try sourcing from your local PC dealer.
