Litecoin Mining Rig Adapter?

I have a spare GPU which I plan to use for some casual Litecoin/Altcoin mining in an old computer, problem is it only has an AGP video card slot , although it does have pci slots for other tings, just not one that will fit my GPU.

(Motherboard: http://www.gigabyte.com.au/products/product-page.aspx?pid=1855#sp)

Are there any adapters that will allow me to put my GPU into a normal pci slot? I have a 600W power supply, so powering it will not be an issue.

Will this do the job? I'm not sure how my GPU will fit in the back of the case with this on, but if it does the job I'm happy.


Thanks
