It might work if you leave it suspended horizontally outside of the case. No tube though, no need.
If only I had the equipment and the expertise I would love to turn the 'unused' side pannel of a case into a large passive heatsink. Might work if you soldered square copper tubes in the back, parallel like in a heater core. Nice fanless system, plus you might get good flow rates.

PS. Why aren't multiple spaces allowed? It makes asci art so difficult.
