converting a combo to a head

[jbjr]

Hi all

I have a kustom 65w Quad Combo which I'd like to pull the electrickery out of and turn it into a head.  Mainly because the combo is so large and friggin heavy for a 'small' amp, and also I want to run it through a small closed back cabinet.

Question is how do I turn the amp chassis into a head? - I've pulled the MDF back cover off and had a look at the innards which a friend of mine tells me look like a standard rack mount sized chassis. (I guess they probably use something standard for all their combos and heads).  Just a bunch of screws holding it in there.

Any suggestions on what is the best thing to enclose it in - without fancy woodworking skills? 

Cheers
JB
