  • Stylish board.
Style: MAG B850 TOMAHAWK WIFI
So I'm a fan of that military green color and love the color of board. It has this neat little lock for gpu it's a push button which is fancy make sure you have it unlocked when putting in and locked when it's in place. Easy setup dual locks for the ddr5 ram and has plenty of space for ssd's.
