After installing the front panel connectors, I see I still have free slots on the mb - both type A and C. Any recommended cards for putting these to use? Both front and rear options welcome. That was a weird sentence.
You have 6 more USB ports on the back.
I don't know how many USB devices you are trying to connect at once, but if the ones in the front panel and the ones on the back are not enough... then get a USB hub and install it on a 5.25” bay on your case. 5.25" USB hub
