expansion chassis help
 

about a month ago i bought 3 protools hd cards, 1 core card & 2 accel cards. the problem was that the cards are pci and cant go into a 2008 macpro. so ive been looking for an hd chassis but cant find any for a good price. the ones ive seen on ebay are overpriced or dosen't come with the complete system

does anyone know where i can find a HD chassis for a good price
preferably a 3 bay one
