physical dimensions for Optiplex GX280 SFF ?

Hi,

 

Don't suppose anyone could tell me the physical dimensions of the Optiplex GX280 Small Form Factor chassis?

 

and yeah I know its more or less an obsolete model which is probably why Dell have removed the system specification from their web site but for reasons that are way too complicated to go into I still need the dimensions for it.

 

I did try asking Dell but 2 days after promising me an answer they still haven't got back to me!

 

Thanks in advance
