You do, but once you own the tools, you can do it again anytime without spending 50 dollars just on the service.
You would need:
The Shrink Wrap
The different connectors (if you choose to change them while you have de-pinned the PSU)
A Heat Gun (sold at Harbor Freight) or HairDryer (probably easier to obtain)
Universal de-pinning tool. (F-CPU sells this)
An afternoon alone.
They charge alot (190 dollars) for what they call "The Works!" Which I believe doesn't include the Molex/SATA connectors? It only says ATX/EPS 8pin/PCI-E.
