3.3V vs 5V PCI

I want to set myself up with an Asterisk phone system, so, I found this well-priced computer. The thing I don't know is about Asterisk's PCI voltage requirements, see: http://www.asterisk.org/hardware . Is one an "old" voltage, and the other one for new motherboards? Which one do I take?

The computer I had in mind is: http://www.ebuyer.com/customer/products/index.html?rb=19077958631&action=c2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=89079

Yes: 5v is an old standard and is now obsolete. The latest PCI standard is 2.3 and use 3.3v. The PC you've linked to will have 3.3v.
