I was making a wb from a thermaltake dragon heatsink - it has about 2 inches of solid 44mm diameter copper inc the grid of pins on the top. It was really perfect, but being circular I gave up on methods to seal it/make lid.

Building up walls from brass isnt the easyest thing. I tryed similar from copper sheet, and I couldnt solder the barbs on becuase the rest just fell apart. Silver soldering will help give it strength though and it allows you to use other solders and colder flames to stop the first bit from unsolderring itself.
I intend to try again with the walls method to make a mosfet block for my nf7-s. Probably wont have any fins given the small heat output, but getting it to fit in place propely and the barbs will be difficult I think.
How thick is the brass? You could use two or three layers of it to build up the lid, instead of
using walls. Easyer to solder too... or you can use screws to seal it.

Brass is good enough for waterblock bases - slightly better than alu but wont corrode, so that might be worth trying.
