[57north-discuss] looking for a small form factor graphics card PCI-e 2.0 -3.0

Hey all, I just got myself a windows desktop machine to connect to the CNC router of Ebay, for a bargain. Unfortunately the graphics card is underpowered and I am looking for a small form factor graphics card to fit in the case, size 17cm by 8cm (or there abouts). Has anyone got any old cards lingering about, gathering dust and that are looking for a new home.  I will happily take it if its PCI express 2 or 3 and can return the favour with some Belgian beers. Cheerio, Wouter
