Just bought the MSI MAG B550 Tomahawk and here's my honest review.

Overall feel of the motherboard is great. It has a sleek design, good color combination, and has a lot easily distinguishable slots. It has a lot of fan slot so you can give enough aesthetics for your pc. It also has Mystic Light that will help control the color schemes that you like.

Cooling is also good. It has a lot of thermal solution already installed in the motherboard.

There are some convenient setup like the pre-installed io shield, thermal pad in the M.2 cover, and a lot of USB and audio sockets to used for.

Overall I'm very satisfied and will recommend it to others.
