Sounds premium.

Also consider 1/2" tubing, the BE aquacoil will accept, the Maze 2 is available for no charge, and the Eheim 1250 has one 1/2" fitting and one 5/8" fitting. You'll need a 1/2" to 5/8" barb and a couple inches of 5/8" hose (Danger Den says 3/8" / 5/8" but there refering to "stretching" silicon hose over the fittings).

Also can you fit a Big Momma or D-Tek Cooler Core (the heater core style units). There 6x7 and the Big Momma is 49.99 + 5.00 to get 1/2", or the D-Tek is 42.99 with 1/2" (it's the newcomer). These tend to cool better, but you'll have more work mounting and constructing a fan shroud.

Between Danger Den Cube and BE Aquacoil, take Aquacoil. More fins, bigger and the flow has been split into two paths so its not a big restriction like the DD Cube.
