I quite like that, I really wanted to get a Z370 TUF mobo but saw that Asus completely messed up the design after their Z97 Sabertooth/TUF, Going for a very non military styled kids toy that looks like it was designed by Fisher Price and then completely removing the full cover "armour" with the Z370 TUF which was an even bigger design mistake IMHO.
And the double coolermaster logo wasn't necessary. They could have used the TUF logo on the other heatsink. Considering the fans are spinning, you don't see the TUF there so it wouldnt be too much.
Would be a great way to show collaboration, Coolermaster oneside, TUF on the other. Nice little partnership design.
