I'm using the Supermicro CSE-M35T-1B with my Antec 1200. I had to use a dremel to remove the tabs in the 5.25 bays. The front fans are clipped to the the 3-in-3 hdd enclosures that come with the case, but you can mount the fans without the 3-in-3 enclosure. I'm not sure you'd be able to use the front fans with any 5-in-3 enclosure that has a backplane because of space issues. You might be able to use the front fans with a bare-bones enclosure (forum thread), but you would still need to remove the tabs somehow.
I'm happy with the Supermicro 5-in-3 enclosures so far. The only thing it's lacking is a dust filter, but I couldn't find any 5-in-3 enclosure that had one. The fan was a little loud so I replaced it with a Scythe and I'm planning on taping up the holes in the enclosure to get better airflow across my drives.
