As a Meshify C owner for over two years now, I can tell you air flow is not very good out of the box. It comes with two dainty little 80 mm case fans and these are barely able to move the air from one end to the other at UEFI-default rpm. My cpu cooler( Noctua) does a much better job moving air. If you can replace the two case fans with two or more larger-diameter ones, then that MIGHT be a different story. The tempered glass side panel is a potential hazard--I have to be VERY careful not to split the glass around any of the four screws when I remove it to swap out my nvm-e drive. So far, it's held up OK but one never knows.
I'm saving up for a new build and will be moving to Lian Li--prob. one in the 011 Dynamic line. This is above your budget (179 USD and up) but is a superior case from what I understand.
