Hmm, not sure where to point you, saxguy. I have the MSI RS480M2-IL. It's a socket 939 microatx motherboard based on the ATI Radeon Xpress 200 chipset. It's full-featured and should fit nicely in the Aria case. It comes with the Xpress 200 integrated graphics processor, but there isn't any AGP support. The RS480M2-IL comes with a 16x PCI-E graphics slot.
