custom branded mini itx enclosure - small as possible

This is a mini itx computer case. the top is fastened by #6 3/8" screws. The taller is designed to fit the Gigabyte G5 gaming motherboard, the thinner one an older intel all in one desktop board. It's branded with the Anti-Red logo which also serves as airflow vents. It fits exactly with my portable battery design: https://www.thingiverse.com/thing:2451285
