My first ever water block, uf that was long time ago I don't even rememver any more, for my celeron 266 cpu that was overclocked to maxumum bh6 mobo allowed 533 MHz using 70W TEC. It was made from two aluminium plates drilled inside (similar to #Rotor, but with no pins and then epoxied and bolted together
from then on I'm strictly watercooled and loving it
