Question How can i mount a Fujitsu PSU ? (nonstandard form factor ! -> P700 et cetera)

[Nice Nicer]

Hello,

i have a Fujitsu P700 prebuilt and i want to swap the case, but i don´t know how.
That's because of the power supply !
The screw holes don´t line up properly with most PSU form factors.
I can´t mount it to another case because of that. I have some Micro ATX cases available though.
I can´t find a mounting bracket for the PSU or something similar.

the specs of the P700 ( normal stuff except the PSU , 2nd gen intel ... )​

Is there some shop, that sells mounting brackets for these PSUs ?
Or is there some easy way to fix this problem?

Thanks in advance, any help is appreciated of course
