My 220 got a chip missing from it and its been fine for 3 years lol. Looking at the pictures its 3/4 inch thick and 1/2 inch thick? That'll hold up perfectly fine.
I'm currently running an OLD SCHOOL 150 with 1/2" plate glass, no braces, and huge chips out of the corners haha, and its in my bedroom with zero issues. You'll be ok.
