PCI Riser Cards and PCI to miniPCI adapter
Most mini-itx motherboards have a PCI slot, but most applications which use the Mini-ITX form factor do not have the clearance to have a PCI card sticking vertically out of it. The solution often is to use a PCI Riser card to put your PCI card on it's side.
The PCI to miniPCI adapter allows you to use any miniPCI application with a standard PCI slot.
