Yamaha DTXpress/DTXplorer/DTXtreme

I've just bought the DTX II and it will be delivered on Wednesday. 
The only problem is that i have very limited room for it. If anyone 
has the rough dimensions of the rack or just a rough guess at the 
floor space it requires then it would be most appreciated. I could 
just wait till it arrives and set it up and make room for it then, 
but that just means loosing valuable playing time.

Thanks

Phil
