Rack mount case PSU...

[poast78]

Hola, amigos.

Yep, I'm still at it, even still, again.  After thinking about it for a long enough time, I've decided to go for a 19" rack mount case, so I can take my gear on the road.  I'm planning on the Ever Case ECR9400.  It has exactly what I need, as far as I can tell.  Here's something that I'm thoroughly confused on, though; what's the deal with the PSU?  It says I need a "PS/2 or PS/2 type mini-redundant power supply".  Well, I was hoping to use a True430, but that now seems to be quite impossible.  I have no idea what to do here.  This will be for the studio, and I'll have a number of PCI cards running off of the main supply, and will often be recording with the machine in the same room, so I need something over 400W and quiet.
E-mailing a few companies has produced nothing.  Bleh!
A guy I've spoken with says he's using a quiet Enermax 431W PSU with this case, but looking at their site revealed no such PS/2 supply.  I've asked him about it, and he's not answering. :-(
I would be happy with something from that company, however.

Thanks for any help.

Contact the case manufacturer for the specifications for the power supply - particularly the physical dimensions.  Then choose a mainboard for the unit to make sure the connectors are compatible (i.e., not all server-class boards use standard ATX connectors).

I contacted them a week ago.  They say that everything I have will work fine with the case, and all they would tell me about the PSU is "we make some".  Their's are useless, and they're not being very helpful otherwise.
