Greetings all. I have started flipping PCs and ran into an issue I need help with.

I'm setting up my first PC, with an ASRock B450M/AC board and a DIYPC Cube01 case. After putting the board in the case, I see it's too wide for the motherboard tray, by about 1.5 inches, and it covers about 1/4 of the fans.

To remedy this situation, I bought a new case that will work for the board, but I don't want the Cube01or the fans I bought to go to waste. I have an old Acer PC that doesn't boot due to either hard-drive or board issues, and it has an i7-6700k and 1070 in it.

After trying to search for a long time, I cannot find a board that takes the 6700k and has an aRGB header. Is there one? Or if there isn't, what are some alternatives? I'm trying to connect 3 case fans and a CPU fan to something that will allow me to set up the RGB.

Any and all help is appreciated. Thank you in advance.
