I looked up his MOBO and from the specs and photos there is no PCIeslot or AGP slot.here is the link.http://h10025.www1.hp.com/ewfrf/wc/generic...cname=c00361570

Interesting:The glue chip ICH6 supports it and I think I see on the referenced photo where on some versions of the mobo the socket could be placed - maybe - unless those four rows of high density blobs up from the PCI slot are just trace through holes.Must be a real economy version.
