Before starting this mod, think about placement and where you're going to plug it in...as I state in my final thoughts, It's a good Idea to have a power strip at the back of the bench in which you can plug this one into. So think about the depth of your bench.
Also I hate that I have to say this, but once the power strip is open, don't plug it in until it's closed again.
Power Strip with appropriate length cord
Drill (preferably powered)
1/2" Drill bit (spade bit will work the best for most drills)
Desoldering wick or tool (not necessary but handy)
Step 1: Open it up
There were 3 security screws and two #2 phillips on this specific model.
