The State of the Überclocker Address – Equals Zero

We begin the build of Überclocker with my favorite production machine, the abrasive waterjet. These parts were made from one of three plates of 7075 aluminum I caught a great deal for on eBay. 7075 may actually be my most favorite material because it''s one of the strongest aluminum alloys, yet you really can''t tell by machining the stuff.
