Trust Mick on this one, in MY case (and probably ONLY my case) that won't work. With my modified cases there's no room for a 120mm fan. The HDD and drive cage are in the way. I have to come up with something a little different to what will work for everybody else.

I've got the little fans running so they're not a problem ... as far as I can hear. If wifey complains I'll have to come up with something else.
