I ordered that flirc case, and will test it out when it arrives. There was a reseller in NZ, but I found a cheaper one internationally. So it'll wend it's way across the Pacific to me, in a week or two.
I still like the idea of longer heat sinks, though. Then I can just use any old cheap case with holes over the chips, or the deep sized cases I've seen. Or that cool looking Rebel case above. Plus it would look weird with long heatsinks poking out, and I like weird. This isn't going to be used for an entertainment centre in the living room, so the weirdness appreciation is just for me
But it will be right next door to my bedroom, so quietness is important. I enjoy falling asleep to music (I set a half hour's long playlist, and drift off). Not so much hissing and whirring.
