This I did not even notice to be honest, ain't the NTSC versions a lot more rare?
If it is a NTSC unit that might explain the lack of PSU, since we use 220-240V/50Hz mains here, could be someone tried them and they blew up or something, no idea ^^
I was interested in buying one from them a while ago, but i suspected it was NTSC versions they sold as the PSU was missing. I tried to ask them, but they said that there isn't any difference between PAL and NTSC models, which i doubt.
Seems like you can hardware mod them to output PAL as standard though.
Here's an EAB thread about NTSC CD32
