@ BKK and TH: nice to see you talking at this high technical level.   

@All: are there any options of watercooling?
user toolhead created a very nice solution for Burnins Board and Burnin will actually directly assemble (optionally) his boards with toolheads Watercooling block.

so it would be very nice if I could use my pump and radiator for all my boards including my TH's K64.
