I want to build a computer case or a tower from scratch how do I do this?

Answer 1

You need a laser cutter or a turret press and a press brake. You also need a powder coating gun and an oven.

I think its cheaper to buy one already made.

Unless you plan to make a gazillion of them...

Answer 2

It'd be pretty cool if you'd carve it out of a log. Chainsaw the tree down, chop you a log, hollow it out. Send me pics when you get it done!
