I am curious: are there users who have succesfully used the Velleman kit K7203 12V/3A to power their pc with a Pico powersupply?
The Pico seems to work very good with a linear powersupply (as far as I know the K7203 is linear) so this kit might work.
My idea is to use 2 K7203 kits, 1 to power the 24pin Pico and a second to power the 4pin-ATX connector on the mainboard.
Question is, will 3A be enough?
