OMG OMG OMG. That block is a work of ART. I'd put it on show at the local art museum! What are the dimensions on that block? The flow chamber doesn't look to huge. Has anyone gotten any static die numbers? How much are they going to cost? BlaH! I'm SO jealous! You machine shop harlots! lol

Oh yeah, go for the copper top, it only adds to cooling power! Plus there's almost no chance of leakage etc. Good work to whom even made that nice piece!!
I wish I had a CNC miller! BTW- Does anyone know how to get rid of this "hot stank" crap... that's going to get jokes, I know it!
