For inspiration look at EZAVALLA's handmade chassis (with limited access to a shear and folder) Click the image to open in full size.
and FROMTHECROWD's "non chassis" made out of standard "window extrusions":

Both quite inspiring:

The whole thread lives at: Chip Amp Photo Gallery

Be sure to check it, it's full of interesting ideas.

Thank you Mr. Fahey for showing here my humble chassis.
Just as an idea I leave a schematic to show how easy it is to build a chassis.

Take for sure you can add as many "beautiful things" as you want, but that layout is the simplest one I've found, even if you fold the sheets by hand ...

I DO appreciate the "blue-print" but saying "how easy" makes me balk. For me Math is easy...............yet others recoil at the mere mention.

To do a 'proper' job, one [I would think] would need an excellent cutting tool [certainly not a hack-saw!], bending tool[I shudder at the thought of doing it by hand], files for removing blurs and rough edges, and the right material !

Not forgetting that getting all the parts to fit 'exactly' can be frustrating.

Then drilling the holes [aligned!!] to keep the thing together.

Then de-grease, and finish.

Nice chassis .... but I agree with KMossman (well, except about the math) in finding metal work difficult. Woodwork, no problem, as I have a complete shop, but metal ....

Case work for me! Although I bartered for a small drill press and that has helped tremendously. Still the metalwork is daunting to say the least. I sometimes think of picking up a small brake for the bending part, but am stymied on a reasonable way to cut it.

Math is EASY! [he smirks]

I totally aced drafting, electrical, woodwork, and metalwork [and Math!] in high school. [the metalwork teacher handed me a book and video, and said, "Teach yourself welding!", after I finished all the projects 4 classes ahead of the others].

BUT! I MUCH prefer to work with wood.

A CNC industrial laser? A CNC plasma cutter? A 10 ton metal cutter?

Beats me too!

making the PCB?
I get them made in China very cheaply.

getting the parts?
Next day delivery.

the chassis and getting it to look good?
Cutting accurately is quite hard.

getting the right layout [in the chassis/cabinet/case]?
No problems if the chassis is big enough.

testing
So long as you are thorough there should be no problems.
