"... so, I thought, why not?"

I hacked my way through a lot of this first one with a pair of Klein nibblers that just weren't up to the thickness of the metal.
 
A rotozip with an angle cutting attachment and a carbon cutting blade made short work of the rest.
 
The mesh plate that Cooler Master installed on the bottom was nothing but trouble, and I can't see much value for anyone in it having it there.
