I got mine in a couple days ago.. yummy.
the enlight case has many more external 5.25 bays (almost double). big deal

the sx1030 has a few features I REALLY appreciate.
3.5 floppy mounts in the NORMAL spot so you don't have a crappy floppy cable running up a foot and a half, killing airflow all the way.
lots of 3.5 drive space. you can easily mount three hard drives with good airflow between them.
fan mounted to the front of the lower 3.5 rack.
rail-mounted 5.25 devices.
drops my temps 10C from my previous supermicro full tower.
...
now, how many 5.25 devices do you have? also, how many are you considering buying? I only have a dvd and cdr right now, and am planning on picking up an ultra plex. that leaves one more 5.25 bay open.
do you have a floppy AND a zip? mount them both in the 2 exposed 3.5 bays. yeah, I know that might get hairy with the ide cable situation unless you have an abit be-6 mobo or the like with 4 seperate IDE channels (8 devices possible).
