I already suggested them. I favor the DPS5005 module because it is the most powerfull of the compact ones (pcb in display module).

MarkF:
I watched Dave's video a while back.  But that is all I know about them.
They look promising if you want to buy something.  One would probably be a better choice to pair up with your HP power supply or the ATX depending on the voltage range you're interesting in.

Edit:
After watching the videos again, my only concern would be that the output is noisy.  It may or may not be an issue depending on what you're using it for at the time.

Pirateguy:
i don't mind some noise, it will just force me to learn about putting filters in my projects n stuff when it comes up.
(does that make sense?)
i like the panel type setup, leaves a lot of freedom over the placement of the binding posts n stuff.
ill keep these in mind for later. for now ima diy it. i feel like this is all stuff i'm gonna need to know about
anyway to progress in my hobby. so itll be worth it just for the experience.

speaking of dave's videos, i found the perfect one for me and this project:

i haven't watched the whole thing yet, but it looks like this will teach me the math i need
for the adjustable one.

anyhoo, wat do you guys mean when u talk about 'double bananna plugs'?
and does the 3/4" measurement have to be exact? or is it a minimum?

Old Printer:
About a year ago when I was needing my first decent power supply I ran across this series of videos where Dave designs a PS. I had a look inside some good quality supplies and was amazed at the complexity of the circuit and components. I realized I was not going to be able to come up with anything like that on my own and started watching Dave's. I don't recall which video number it was, but 3 or 4 into the series he started running into complications. As I recall he kind of lost interest in finishing, or at least overcoming all of the problems to his satisfaction. This is very loose recollection on my part so don't quote me, but it was at that point I set my sights on a good commercial PS. The nice HP's were too expensive so I headed to the used market. Seven PS's later I think I have enough for now :) They can be an addiction.
