hey, i actually used a meshify c for my last build a couple years back. for airflow, it's still pretty decent honestly, especially if you slap in a few good fans. the front mesh is really effective. not exactly cutting edge compared to some of the newer stuff like the fractal pop air or lian li 216, but it holds up well. depends on your components too, like if you're running a super hot cpu/gpu. but for most mid-range stuff, it's totally fine. still looks good too imo.
