Liquid cooling has become quite mainstream. Heck, even liquid cooling
overclocked PC CPU's and GPU's isn't uncommon. I can walk into the local
MicroCenter and buy everything I'd need for liquid cooling a PC. Granted,
an RF PA would have higher dissipation than a PC, but we're not talking
about giant heat exchangers, copper plumbing, redundant pumps, flow meters,
etc. like we have in broadcast. The costs aren't unreasonable, even for an
amplifier built for the oh-so-cheap amateur market. And when you consider
that one cooling system can serve multiple amplifiers, it becomes that much
more attractive.
Just think - you could go to your local car junkyard to get the heat
exchanger (radiator) for your new homebrew amp for twenty bucks :-)

At least it gives us, and the equipment manufactures, a chance to stock up
at the current market price, even if nobody else picks up the product.
