1st of all I'm terrible with the finer hardware stuff and the names of this stuff.
I have converted a mini pc into the case for my Kryoflux and its two floppy drives.
The power supply in the case works fine for that purpose, except that it makes a high pitch noise and is probably overpowered as I just need it to power two floppy drives.
So can someone help me find a replacement that I can slap in there? Best would be a parts shop in Europe.

Or maybe even better, point me at a forum that is more specialized in that.
