The biggest concern with modding the cabinet is air flow. As long as the "box" remains sealed, you should be OK.

On another note:  What appears to be the problem with the MB?  It is rare for these to fail.  If you are in the US, perhaps I can repair for a reasonable fee.  Contact me offline.  I may also have a few spares around.  Shoot me some details.  Let me know also if you find a cheap/free DS15 as I could use one too...
