recentally some of the antec cases were screwed up and some people that ordered sx830s got a sx1030 with a sx830 bezel, so they ended up getting 6 int 3.5 bays, so you might get lucky and get one of those
anyways, last time i checked the sx1030 was only about $15 more than the sx830
i have a sx830 and love it, wouldve gotten the sx1030 cept i dont like doors, even though i may be getting a chenbro echo because its the only case i can find that will fit all the crap i need to fit in my next computer
