Thanks for the info Alewis,
I did measure up some chasis / cases and because of the board riser(s) *first the Z4 and then the Z4PCI it forces the cards up quite high, I believe the dimensions needed are as follows.
X = 45cm (width)
Y = 14cm (height)
Z = 35cm (depth)
all the boxes i have seen on ebay seem slightly short in one or more dimensions.
Its a pitty i binned an old 386 desktop chasis, would of been perfect today
