Help me gut my BOSS!

:) Interesting subject title, no?

Anyway...I am getting ready to pull the steppers and clean out the
CPU cabinet. I am planning on leaving the limit switches, spindle
power intact...

What should I keep? What gets yanked and put on the Ebay pile???

I am going to set this up for servos & Mach2 & will most likely build
a new power supply for the servos. I have only jogged the machine
around (without hitting the limits) and the Y axis lost the magic
smoke AGAIN...I'm not replacing another one of those transistors
all the way down in the bottom rear of the cabinet!!! Time to
gut!
