Rackmount VAX6000 cabinet: http://www.docsbox.net/garage/tn/VAX6k.jpg.html http://www.docsbox.net/garage/tn/VAX6k_2.jpg.html Plus you'd have the expansion cabinets - this chassis is just CPU & RAM. I understand that the rackmount VAX6000 is a lot less common than the full cabinets, but I've never seen the other. I *think* the cabinet model is about the size of a DEC7000: http://www.docsbox.net/warehouse/tn/DEC7330a.jpg.html http://www.docsbox.net/warehouse/tn/DEC7330b.jpg.html There's no size reference there, but that cabinet is about 5'8" tall, 36" deep, and about 40-42" wide. One of my friends will suffer apoplexy if you score a rackmount 6330.... Doc
