Switching Power Supply in EC 2

Don Brown KD5NDB posted (2002) an interesting proposal to install a MFJ-4125 power supply into an EC-2 Case.  Has any one attempted this project?

Hi

Although I never got around to it, I did some measurements and the power
supply will fit into the EC2 if you remove the rubber feet on the bottom of
the power supply. I guess you could also remove all of the electronics and
fan from the case and install it all into the EC2 and have even more room
but that should nor be required. All that is needed is to cut out the back
of the EC2 to fit the power supply and drill come holes in the bottom of the
EC2 for air flow. There is even enough room for a K2 type battery that could
be float charged from the power supply and or a solar panel with controller.
This would give you a back up supply in case of a power failure to run at
QRP levels. A while back someone on the list posted some pictures of the set
up with the power supply in the EC2 so it has been done.
