because the baybus circuity takes up the whole inside of the drive bay, so it wouldnt fit

I have 3 5.25 bays on the front of my system and they are all occupied. I want a MO screen though. One of them is occupied with a 4-port dual voltage baybus, and I was wondering if there are any MO screens that will fit in a 5.25 bay and can control 4 fans? Thanks
