Case-less case; why waste space on sheet metal when I can use the heatsinks for everything? These are not even expensive, and the form, fit, function - it's all there.
Let's see, open like a Portugese chicken
There's really not that many parts in the F5! And what is there, fits perfectly into the dimensions of this:
http://www.mantech.co.za/datasheets/products/39663.pdf Internal height 36mm, caps are 35mm.
At the "rear" of the
case, 60mm of the transformer plus the wiring that sticks up from the transformer fits into the HS double volume like a glove.
Left-rear of the
case gives me prefect space for the wiring and rectifier bridges - that run as hot as the MosFETS, I'll have you know! So, they get to stay on their own HS which acts as the case-bottom.
PCBs occupy very little of the "height", even with all the wiring that goes to the PCB.
Nice.
Now, this is the idea of PSU caps wiring (no more PCB):
Before you even consider this fancy
power resistor work, you'll need a
Bantam Magnum, bruuu; best with a 5mm tip:
The additional small caps that see you are the secret to zero impedance of the last segment of caps in the F5 (R/L)CRC PSU configuration.

Lets close the
case (please note the dimensions - I promised you slim some time ago...):
