I replaced it with Apogee XT to make some configuration changes and it needs a new home.  Swiftech Apogee GTZ block with LGA1366 mounts and 1/2" ID barbs.

  It comes with a new mounting plate, black hose clamps, and a tube of Arctic Silver (I think Céramique but it is unlabeled).

  It is in great condition, I cleaned it after removal so it should be ready to install.  This is a high performance block, the reviews are excellent.  Swiftech has great customer service and makes some of the best blocks.  I am a total hardware snob and use Swiftech blocks exclusively.

  It is the block that has the really easy to install thumbscrew system Swiftech has, kits for other mounts are available from Swiftech or a vendor like frozencpu.com.
