The ASUS Prime AP202 is the newest microATX case in the Prime family. It sports a bent glass panel and patented slot vent to separate the PSU/storage compartment from the rest of your system while still offering good cooling. With quality in mind, this case may cost more than other microATX cases but could be a great fit to those who want that sturdiness and design in a more compact size class.

The CPS PCCooler K101 Mesh clocks in at just under 12L in volume, making it a very compact, air cooling focused SFF enclosure. Offering the usual sandwich design, it manages to stick to the functional basics, but also includes three slim fans, so you can spend the rest of your budget on the best components possible.
