TEK 6.66. They look great, but I saw Duniek to be the first one to post " bigger volume" pots. With a Alu extender at top, but I don't know..That was a week or two before Kinping's 5870 WR. He wrote that his 5870's where cooled by TEK 6.66 in is HWbot submission...
Hopefully my friend will order one pretty soon, can't wait to try some singel 5870 action.
