The one thing I have not had to replace is the power module. I do not know how difficult it will be.

Hi cholan,
If you can swap a hard drive then swapping a power supply should be no problem. 4 screws and a lot of connectors.
But it has to fit. A full size power supply may not fit in a smaller case.
And, yeah, Sandeep usually does have great ideas.....
