Personally I wouldn't go for wood - metal provides better grounding and 
electrical noise immunity.  But Jack's idea in general is a good one. 
PC cases aren't some mystical black art.  Just hack away at it till you 
have something you like.

A couple examples - for my own machine, I chopped up a large tower case 
into something much smaller:

On the Mazak that we retrofitted at the CNC workshop, all the computer 
parts are simply mounted to a flat plate, which we attached to the 
inside of the cabinet door as you can see in this photo, to the left of 
Dave Engvall's head: http://fenn.freeshell.org/retrofest/dcp_0366.jpg
The strange blue glow in the upper left corner is from the tacky blue 
LED fan on the power supply.
