Is there any kind of estimate on when a passive sink would be available? I really like it with the Caldera system for the 4870x2 and with it dieing this weekend I just placed a order for a 6950. If you hope to have it out with in a month I think I'll hold off for the passive heatsink. If not I hope someone takes some pics and does a personal review of the full cover block soon. The CS folks over at Swiftech have sent me a lot of free parts when I've striped screws or had other issues that I'd like to stick with Swiftech.
