You can even use a thick piece of aluminum and just drill some holes through it the long way and hook some radiator hoses up to it.

I've also seen where somebody uses a router to carve into a block of aluminum, and puts some sealant on it and puts a thin aluminum plate over the top of that.

Either making something or buying something that's already designed for it, either way, it's pretty straight-forward to take a home-built controller and make it into a liquid cooled one.

Just to note, I've NEVER had a heating issue on my 500 amp DC controller, using just the stock aluminum plate heat sink.
