I need a 5 1/2 inch bay device that has an intake fan and USB ports, maybe firewire port too. I DON'T need a card reader built in. It's kind of an odd combo and I am having a hard time finding what I need.
You could build it! Get one or two 40mm fans and some usb ports that have the header to plug in the MB. Put it in a spare 5.25 drive cover. Might be hard to find that.....
Seeing that the thing you want isnt easy to find at all, making it yourself would be the best option as said before.
If you do plan on making it yourself, and if u have the space for it, I would rather use a 80 mm fan, instead of those 40mm ones as they can be very noisy.
