I have ordered from DD several times and have been happy. My only beef is it takes so long to get things shipped (3-5 days). The product comes as advertised and works.
I also use 2cooltek, CoolTechnica, pcnut, and servercase for other things and have had nothing but great sucess.
FIXITT - any ETA on more blocks? I another rig I'd like to watercool and want to use a Spiral.
