Yea, everything PS linked to is expensive but it would probably be good future proofing. That way when you don't need a certain drive you can just yank it out, downside is keeping track of what is on each drive i suppose.
My intent is to get my act together and start using a setup like that. Need to swap everything into my TJ07 from my P180 though. And that means watercooling too, as the TJ07 isn't that great at direct cooling...
The only thing different about those bay converters from the one I already have is that they are hot swappable. I don't really mind pulling out the unit to replace drives. I'll post results once the new drives come in.
Um... from the picture your bay fits four. The three I linked to fit five... extra drive in same amount of space...
Something like these?:

Something like that, but it was hotswappable and fitted five drives.
Or one of these.

Windows home server or similar on it (seems like lots of people use WHS with this case on [H])
Want. Would be useful. Noisy as hell, though, if it's a typical datacentre case.
