Does PCI cards fit in PCI 2.0?

[Wlau21]

I'm sorry if this is a dumb question but I'm contemplating between a microATX and ATX motherboard. The microATX doesn't have PCI but the full ATX has two. My question is do PCI cards fit in PCI 2.0?

these are the two motherboards i'm thinking about getting. The microATX is still upgradable to crossfire/sli and a very nice MB. I'm thinking about putting one of these into a cooler master elite 360/361 with a HD 6850.

Hi there wlau21,

In a word, no.

Although they share very similar names, they are not compatible, or interchangeable. The slots are physically different, so they wouldn’t fit even if you tried.
