I have seen (a lot of) PSUs with the cooling fins directly in contact with the casing. In one case the case was even tightened to the fin with a screw.
That is why there is rubber (or something like it) for insulation beetween the mosfets and the fins. And that is why I always ground the fins properly when modding PSUs like this.

And about the choke. Has anyone seen those chokes in older power supplies? no. For exmple I have not seen a single AT-psu with a choke. New more powerful psus have those chokes because they need to meet certain standards that they may not cause interference, "ripples" in the electrical network. The choke comes necessery when there is for exmple 20 computers in a single room, (schools, etc) as the ripples caused by all the switching psus would be enormous. Modding a single, or even two computers this way in a normal household causes no problems.

edit: I have modded PSUs like this before. In my own computer the modde psu has now lasted about 2 years without a problem. Thinking about computer hardwares life cycle, I do not require my Psus to last for ten years :)

Voishan niitä kuvia tietysti lisää ottaa..
Tuolla minun sivuilla missä tuo kotelo oli alunperin esillä on pari kuvaa enemmän ku metkussa, mutta ei kylläkään pohjasta.

Old mod, but still could be used today :D

I was thinking why you didn't use any insulation at the edges to prevent the air from blowing out?
You would want as much directed air as possible, right?

Also, I tested with some 120mm fans that are fairly capable of blowing big volumes.
The distance from ground up to the fans is important as the cfm falls greatly within 3-4 cm (on my fans).
Did you test this before lifting your case? Difficult to judge from your pictures, but it seems
a bit low.

Starting next week I'm excited about this project. Thanks for sharing!
