Love the photo of your ANTminer rig.

Looks like you've removed the aluminum heat sink that comes with each ANTminer and have attached (screwed?) each ANTminer to your massive heat sink block (6 ANTminers per block). Did you have to drill pilot holes in the big heat sink block? Did you use metal or plastic/nylon screws to attach the ANTminer to the block? Or did you just use thermal paste to 'glue' the ANTminer to the block?
