Summary

Recycle an old HP DL380 G2 server power supply into a bench/hobby power supply.

Instructions

After modifying your recycled power supply to be always on, just print, wire up female bullet jacks, and you have a tidy looking 12V 32A power supply. Hold the 4mm bullet females in with set screws or hot glue.
My 4mm connectors had an outside dimension of 5mm w/ a 5.5mm shoulder.
I've created an additional version for people with 4.75mm connectors without a shoulder(much more common)
4mm M/F sets are available at any online or local R/C hobby store
Both version have an outer lip that should retain the outer edge of any 4mm connector.
Keep wire length to a minimum to avoid fan contact.

Fits HP DL380 Generation 2(ESP113) possibly others.

Cool. How loud is the fan on this power supply?

I plan to remix this design and shove an XT60 connector through the top of the case to allow for this to be flat on the table.

Love this design!

I d also love to have a remix with XT60 any update?

Did you end up doing the xt60 remix? Id love to get a copy if you have.

I think I will mod an on/off switch into this and a pot (per the schematic) to control the fan speed.

Wanted to see if you did anything to reduce the noise of the fan. Currently, I put two 1/2 watt 47 ohm resisters in parallel with the red lead on the fan. I found that if the value is too high, the power supply will not detect the fan and will not power up. This seems to cut the fan speed by half.

No, I've never attempted to do anything to limit the fan noise.

Thought I would share this too.

It's my understanding by alot (with exception to one) of conversion tutorials that you don't need to connect pin #13 to the +12V plate on the opposite side— is this correct?

Nevermind. According to the user I was viewing, Pin #13 he had confirmed isn't necessary. Best.

I would love to know what that thing beside the Line Filter c14 plug where the AC lead in goes is—it's like it's soldered to the Hot and Neutral wires leading down to that lead to the pcb

the +12VRS would lead to the opposite side +12V and apparently stabilize the +12V signal; I saw it posted on another build in here
https://www.rc-monster.com/forum/showthread.php?t=27554&page=5

but on the more popular build thread for this PSU model it only shows the pad tinned and not shorted with a wire between the two sides.
I guess it's an optional step, but only mentioned on this site here from what I've found searching google so far:

Hope this information is useful.

Can you recommend a source and part number for the female connectors? Great thing, just ordered 4 of these PSUs and can't wait to print out!!

The new revision I uploaded should work with almost any 4mm female sleeve.

The polymax 4mm I have on hand would fit the new version pretty well.

In the end source whatever you can locally, you can just glue or/and screw the backside, the front side will still look clean.

If you don't have anything locally, it looks like the 4mm venom (VNR1632)connectors at http://amainhobbies.comamainhobbies.com would work.
