Second motherboard, I’ve owned
It didn’t give me any issues at all. It comes with the RGB and it looks really nice for the price you can’t go wrong.

Very good board for the money. Bios is simple and easy to understand. Worked with my 5600x out of the box.

Great starter MB for the price!
This is a great starter MB if you are looking to dip your toes into customizing and building your own gaming rig. Not too expensive but modern enough to fit newer memory and storage (I use new RAM and the m.2 for storage), I've tried both Radeon and Nvidia GPU's and both works great. I initially used this MB to build an entry level gaming pc for my brother-in-law and will look to something similar or maybe even the same one to build one for my son. Definitely would recommend.
