Dustin writes "A lot of people modify computer cases, often requiring them to cut intricate custom designs in sheet metal. For most, there is the Dremel tool. But sometimes, that just isn't good enough. Possibly due to an insanely complex design, or unsteady hands, a Dremel just might not cut it (pun honestly wasn't intended). JimBob, a member at OverhauledPC.com, has a much better way. Using readily available salt water and electricity, his technique is much easier than trying to cut patterns with a rotary tool."
