I have a wanted listing for 2 waterblocks if anyone has any forsale. Reguardless, if I have to buy them new who makes a good waterblock cheap? Zalman looks like they used a copper base with an aluminum cover. Congrats Zalman you made a battery! :shadedshu I'd prefer all copper. Maybe a one piece to avoid any o-ring leakage. What are the odds I can find one for $30?
