My PC is an HP Pavilion d400e. The site only refers me to a reseller that is far too big for this Lil fish. I got a recommendation from the hp site, but dont know much of the jargon:
Motherboard (system board) - Amberine GL6E - Includes three PCI slots, two SATA connectors - Without ATX extender card
RoHS: Original
From the back the mobo is on the left side.
