Besides that, how could I find out the pinout?
I would imagine its out there somewhere, but didnt you want 150W anyway...

How about raise the mobo up, and fold the GPU under so it is in its own separate thermal zone? If you put the GPU under, can you cram the PSU beside the mobo, and then have room in front front for a couple fans to blow air back over/under the mobo cooling everything?
Yes, and that is why I initially started looking for an iMac 21.5" PSU. But it really was impossible to find the pinout. OEMs responded to my e-mails like: "This is a confidential Apple part, we cannot share such information"...
Wouldnt it be possible, in theory at least, to ping all the outputs with a voltage tester or something and work it out that way, or am I thinking too simplistic about it ?
It just struck me that there are small PSUs out there and plenty to go on at ebay and the like, which would be good for a build like this.
Update: thermals testing
I measured thermals for four configurations:
#1: On the bench, 4765T CPU (35w) + Radeon 6570 dGPU (60w)
View attachment 93395
idle temps: CPU=35, GPU=32, SSD=24
stress test: CPU=61, GPU=69, SSD=32
idle power=35w, load power=95w
#2: inside the case, 4765T CPU (35w)
View attachment 93396
idle temps: CPU=40, SSD=29
stress test: CPU=75, SSD=43
idle power=25w, load power=70w
#3: inside the case, 4765T CPU (35w) + Radeon 6570 dGPU (60w) (horizontal)

idle temps: CPU=46, GPU=45, SSD=38
stress test: CPU=60, GPU=85, SSD=43
idle power=35w, load power=95w
#4: inside the case, 4765T CPU (35w) + Radeon 6570 dGPU (60w)

Some thoughts...
1) It is very interesting to notice the max temp of the CPU when HD4600 is activated: 75 degrees! When the HD4600 isn't used (#3) the max temp is only 60 degrees despite the fact that the CPU is next to a burning hot GPU and of course the whole case interior is also very hot.
2) The max power draw figures are also very interesting: although 4765T is a 35w part, it seems that this is valid only for the CPU part, otherwise I can't explain why the total draw during the stress test is 70w! When the dGPU is used then we achieve a more easily explainable 35w + 60w = 95w total draw.
3) It is obvious that no part can run at 85 degrees in the long term. So now there are two ways to go: either I completely skip the GPU, or I try to make a custom cooling solution, ventilating the hot air towards a rear exhaust, out of the case, like guru suggested earlier. Now if only I knew how to do that...
4) While in idle the system is almost inaudible (in any configuration), as you may have guessed with these temp figures it is quite loud.
5) There is another workaround, albeit with a major compromise in my initial design plans: I can mount two 60-80mm fans in the front of the case, pushing all hot air to the rear but this means that I forget mounting the PSU inside the case and use the system with an external brick.
Have you looked at the high binned Xeons? They have some that run 25w, and around that range.

Other than for the gpu, expand the fins so you spread the heat away. You could bring cool air from the back, and vent it out the front with say one or 2 small fans at high RPMs.
Depending how much room you have left, put the gpu over the motherboard and the spot next to the motherboard you can get a small fan to vent in cool air. If you're really daring, you can cut out little vent slots from the bottom and have the cool air come from under the case and put the case on say 1/8" pegs or something to raise it up to get that cool air. Cool air is from the bottom, then you can still vent it from the front.
Hi There, Just catching up on all the posts. Can I make the suggestion that you retest #4 above, but remove the Main PSU from the case, you seemed to have explored every option (including removing the GPU altogether), except this one.#4: inside the case, 4765T CPU (35w) + Radeon 6570 dGPU (60w)
