Ill post my PM response here incase others want to know.
"At the moment i have 2 controllers on the outside (attached by double sided tape) on the back where the rubber grommets are and 2 inside the case. Im planning on running all my controllers on the outside so i have the ability to be able to control them just waiting on extension cables. Once TT release the control software (man i hope they do) all the controllers will be inside out of site."
Cheers
Blak.
