@IamSpartacus if you are looking at something like that 3bay (non hot swap) you may want to look at the rosewill 4x3 drive cage and norco has a 5x3 drive cage. the Rosewill 4x3 drive cage does fit in 5.25" bays (they're turned sideways in the Rosewill RM chassis). You'd need smooth sides in your 5.25" bays, ie. no shelves per bay. Looks like you may be able to spray fan frame white(?) maybe with black fans behind it? I've not used these and there are comments about trying to mount them in 5.25" bays - some dremel work may be required? I'd definitely read the reviews and see if there are some comments in some of the system building sites.

I've seen both (and knockoffs) on eBay.
(I was researching these bays for a build - went a different direction so did not purchase any).
