I had peanut oil (1 L), some resinite film (lots) and an urge to open up my psu.
After fidling around I thought that maybe if I sealed 5 of the 6 sides of the psu with TONS of resinite film, I could then fill it up by the last open part with peanut oil! Then seal the top and boot up my pc.

BUT

Experience allowed me to gain wisdom and with this wisdom I was able to control my urges and put back my psu together (normally) and boot up my pc. This way I could come and ask you guys what you think would happen

.
I was also unsure about what I should do with the psu fan ..

Did my acquired wisdom save me from a disaster ?

hmmm, well everything seems like it would work, and u woulnt need a fan if it oil cooled.
but i dont think its a good idea anyway, in that i wouldnt do it,lol
seems like it might work though
do u have a back-up PSU

Yeah I got a psu in my second machine that I can use while I go buy an other one if something bad happens.

The only problem I found with the resinite film is if I use a fan .. I fear that some day it would just stretch the film to much .. but then again, if I put a lot of it .. it should take a few years lol.
I was thinking of keeping the fan to have the oil circulate .. but it's probably not needed.

Good thing I didn't. I forgot about the switch that mecanicly clicks when power is turned on ..

I think I'll isolate it with silicone and then try .. maybe on sunday.

Success.

Resinite film wasn't good though .. now my power supply is in a coleman cooler box beside my pc ..

I need a better set up ..

ill be testing for stability with prime95 ..to see if all voltage regulations are going well.

You guys have any tips on how I should Build a leak proof case for my psu, so that It doesn't have to be outside my case ?

I don't no much about leak proofing but my best guess would be to make a metal box for it, I'd say aluminum sheet metal (much like an oil tank for a bike) and cut a hole out for the leads out, now to leak proof where the leads come out I say coat the leads in duct tape/or tubing, then cut out some roofing felt to the shape (a couple of them like 2 each side) and use roof tar with it and layer it like a sandwich on both side, and go around the edges with a sealant maybe silicone/epoxy…I've felted a few roofs before and felt is soft/flexible, but with tar it can be very water tight…

Only issues with the above is tar/felt smells for quite some time
And would add weight to the psu, especially with a metal box
That and making the box above would need a mig welder of some kind.
(plus tar when warmed up can go soft and alter its shape, like melt/reset, melt/reset each time its heated up so could lose it leak proofing properties.

Second option would be plastic, measure your psu and add a few cm's to the measurement templates (for when you join them) and melt the plastic together,
It'll be more water tight then gluing and reinforce all the joins with epoxy resin
Using some kind of sealant like silicone around the lead out hole (basic same method above) but using tubing around the leads out like a rubber ring and seal around it (by the plastic) with epoxy resin first and sealant after …

Issues, which this option is it'll add to the size of the psu in general, and against a metal case, could wear away if removed often, and make sure you use a thick plastic (not a lunch box or anything thin)

But the second option is the best in my view, but I've never had to build a psu leak proof case before so I'd ask someone with more experience first

hope this gives you some idea(s)

EDIT: like sideburns and aucher say cooling is an issue,but copper (solid) is expensive to my knowledge,but copper piping (as used in centeral heating) isn't so if you cut circle holes to the size of the tubing and put it in contact with the psu and either (depending on option) weld or glue/seal around it,it would act like heatsinks,i think/guess) and you could add as many as you could each side (dont have to be long),you'd have to seal the end, welding would be ideal,but sealing would work ok i guess.

well you have to water proof...but you also have to dissipate heat. SO, keep that in mind.

If you can, get some copper sheeting to make a box. Be careful of those flux fumes though... If you have any laying around, put some copper heatsinks on the back where the fan used to blow out. If you want to get tricky you could put a aluminum sheeting on the sides that would be inside the case so there is more resistance on those sides. That'll help pull the heat to the back where the copper with heatsinks is exposed to the air. That should create a natural flow of the oil as well.

I'll have to look into doing this myself... Heh.

EDIT:
The only thing you'll have to do after this is make sure you have plenty of air being pulled from the case. A lot of the air get pulled out through the PSU so you'll have to make up for this. You could always put a 120 mm fan where the PSU was and put the PSU in the bottom of the case.
