The cost, both purchased and operating, would be lower. I guess that's why some things ya gotta do yourself. It's also why I won't be running a pre-built system any time soon.

Dunno whether this approaches the description but:

I have made a simple 50 x40 x 0.8mm chambered Copper waterblock ,with 6mm thick base which should give a velocity of ~ 1.7 m/s at a flow rate of 50gph.(hope my sums are correct)[Edited sums on Oct 30th(changed from the wrong ft/s to correct m/s).



Unfortunately this easy to construct "flat" geometry has a high flow resistance.
Flow rate ( radiator in separate cooling circuit) 25-30 gph with 600 lph (unknown max head) pump,and 45-50 gph with Eheim1250(1200 lph, max head 2.8psi ).
Cooling a Morgan1100 and stressing CPU with Jouni Vuorio's Stabilitity Test got( 3 seatings):



Intend to disassemble wb and fit with central water inlet to look-see at the infleunce of "Die Area Impingement".
