If you used oil, you could build something smaller (at least if you
don't count the tank). The 2nd cluster gets sufficient cooling from the
natural convection which develops in the channel (no forced convection).
The same would hold for water. It would be fun to try, but I think air
is more convenient. But even with air you can build small systems. Check
our "third HTPC", which would be hard to build much smaller even with
water-cooling (or oil for that matter).

sry for another post but i just got an idea. im not sure if you have
seen that you tube video of a guy who put his whole setup in a fish
tank and was using cooking oil i believe to cool everything. would be
interesting to see the 2nd cluster put into a big enough tank and
cooled with oil.

In this case we have large "home made" heat sinks, I'll put up
more pictures when I get the time. You can check other designs at
www.renget.se/gallery.html <http://www.renget.se/gallery.html>
In contrast to our "Second cluster" on that site, which is
completely fan less, this has two large fans. By using the
fans one can get adequate cooling in a smaller box (than what
would be possible without fans).
When I get the time (when?) I intend to do combined cfd/heat
flow simulations of our designs (have a PhD in numerical
analysis).
Eventually we hope to market this.

is one of you an engineer? how well does the air flow in the
case. what
gets air into and out of the case if there are just only 2
fans on the
box? you guys ever consider marketing this product?
