You can purchase commercial aluminum chassis and rack panels.  The 
shielding enclosure can be made of aluminum angle and sheet stock 
available at a hardware store.  You will need a good vise, a hacksaw and 
a collection of files.  Although you can drill holes with a handheld 
drill, a drill press makes it much easier to do a good job.

There are many sources of prefabricated chassis components available on 
the net.  For one example, look at <http://home.flash.net/~k3iwk/>.

For examples of good homebrew construction, look at old ARRL Handbooks.
