How do the ATCS 840, Cosmos 1000, or HAF X chassis stack up with the Cosmos S that was suggested? I need a case that can fit one optical drive plus up to 8 HDD's along with ample cooling of course. If some additional HDD cage modules are needed, I don't have any objections to that. Coolermaster certainly does seem to have some nice huge chassis that would seem to fit my needs.
