Thanks for the replies.
Blackeagle, I have a MCP600 at the moment and love it. Switched from a Danner Mag3 which was too big, too noisy and was mother to get sealed.
I'm looking to add 2 HD blocks for my scsi drives that's why I want to improve my pump to something more capable of handling a CPU, GPU, NB, and 2 HD blocks. A lot to ask of one pump. And the price thing isn't really an issue, I've always been of the mind that if I buy one of the best on down the road it will save me having to buy 3 or 4 cheaper ones. I like quality in other words
As for the heater cores, yeah that comes down to looks. I want something that looks as much quality as the build is. Heater cores are just too ratty looking for me. If they weren't so expensive I'd get a Fluidyne heat exchanger for a shifter kart. VERY nice rads with -AN bungs and better build quality than any comp rad or heater core. They are around 300 bucks though

Compared to that the Thermochills are cheap
