The lack of RGB should add one full star to the rating.A rating of 3.5/5 seems harsh, since for many people (myself included), having not RGB is a plus.
I bought this board over the Gigabyte Aorus ITX for precisely one reason: USB type C header. Compare with ASRock and Asus ones, this board is cheaper with no sacrifice.
Having said all this, a common complain people have with this board is its cpu back plate. It's not a problem for me since I'm using it with an AIO (NXZT H1), but it won't fit many others that require installation of custom back plate.
