This is a fantastic sound card which has an external box. It plugs into your PCI socket, and has a cable that connects the external box to your PCI card.
For more details about the card itself please visit a review at http://www.techspot.com/reviews/hardware/gametheaterxp/
The hardware comes with the original installation disc which includes a certificate of authenticity. Note: newer drivers can be downloaded from the original manufacturers website.
I have used this sound card for a few years now, but I currently have a "narrow PC" so the PCI card will not fit into my current machine.
The item is £25, and can be collected from London, otherwise postage is a further £7.50.
Payment is via paypal. Postage is £7.50.
