[sdiy] diy modular power supply

[ahlist]

Hi,

Does anyone have good instructions for a diy modular power supply?
Any format is ok. I have no modules yet. The price of most
cases + power supply is very high. I can make my own case. I'd like to
be able to make my own power supply (or find something much cheaper).

I've searched the archives and not came up with anything recent.

Has anyone tried to convert computer power supplies or other cheap,
easy to find power supplies into a modular power supply.

Forgive my ignorance.

Thanks.
