I have always liked DD blocks. Their full cover blocks have always been top notch. They only have been equalled by EK and that says a lot.
As for covering VRM's i think the hybrid waterblock / heatpipe solution may work nice enough. I'm just wondering how it would do without airflow (most likely in a watercooled case)...

DB, how much weight does that new block add compared to typical delrin/plexi topped full cover blocks ? I guess we'll have to start using those card holders that come with some cases...
