This was one of the last items I settled on and set the white and black theme for the build. UEFI is simple to use and easy to flash. Otherwise, it could use one or two more fan headers, with only four it might be hard to run a loop without a fan controller. mATX with the best options, White leds don't really matter to me but I will add a strip in later.

This mobo does everything I need it to do, and looks great with the build. Runs my Corsair RAM at 3200 after updating bios, which was quick and painless to flash. The only negative thing I could say is that I probably could have got it for a little cheaper if I'd waited for a sale, but at the price I paid it's still worth it.

The motherboard is asthetically pleasing, though a little annoying the IO panel is the same as the non-white version, and doesn't fit the color pallet at all. Doesn't matter too much since it is in the back, but that is the only real complaint hardware wise.

I had to knock off a star because of the BIOS. The first boot took way too much troubleshooting, and there seems to be a problem with the board with the first boot. I had to try a bunch of things, and once I cleared the CMOS I was golden. Be wary and ready for trouble.

Great looking board for a white build, plenty of PWM fan headers and a flat USB 3 header for better cable management.

There aren't many good priced AM4 Micro ATX motherboards on the market currently, but even if there were this is one is pure quality.

Well featured Micro ATX board... and not many other Micro White choices ;)

Not really much to say here, it pretty much just fit my color scheme quite well and was compatible with my CPU so it's what I went with. No complaints!

Good looking motherboard. MSI's BIOS is great. LED's were a tad underwhelming, however, it was a great mobo to work with.
