Finally found a pic of it. I'll try to find some more so you can see placement of the disk drive.. Also again like I've said before this is the keyboard Yamaha used as the basis for the body design for the 9000 Pro.. Look at the end caps too.. The Pro has the same pitchbend and modulation wheels too, and used the exact same keybed from this one.. This keyboard was a BEAST for music production.. The synth sounds on this thing and the voice editing possibilites were scarey. This silver version of the EX-5 was never availavble to customers in the US... Here's the link.. Not in english of course....
