Small Form Factor PCI riser for 32-bit 3.3v slot

Hi all

I've searched and searched with no luck.

I need a 3.3v 32-bit PCI riser for my mini-ITX motherboard. All the 32-bit risers I can find are for 5v slots. Am I right to believe that the contacts and notches for 5v and 3.3v are symmetrical? Could I buy a passive 5v riser and just plug it in backwards to give me a 3.3v riser that positions the card over the motherboard (component-side up)? That would be perfect.

Thanks for any help. Apologies if I've overlooked a thread that answers this already.

Perhaps I've posted in the wrong forum? Any suggestions? Thanks

 

Goggle is your friend...

This shows one, not in stock, but shows an HP part number...

...it's a starting point.

Google also turned up a lot of 64bit risers - I assume your PCI slot is a 32bit slot?

Edit: found this (http://www.mini-itx.com/store/?c=8) - can't see the specs but they do have a few to choose from.

 

Take a good look here. These guys have riser cards in all flavors.

 

Thanks for your help, chaps.
