Re: My super cheap semi-diy PC desktop system:)

I am so far removed from my engineering math skills I won't even try to go there now. However IMO this is one design where it will be very easy to go overboard with good success. The ouput cap should be as big as bloody well possible to keep ripple as low as you can. Inductor size depends on power draw but I'm thinking 10mH should get you in the ballpark but bigger will always be better here. The input cap will likely be the power supply output filter cap which should be fine.

Did I say that output cap size being big here will be important? because it will.
