Looking for specific case...

Saw one at a custom build shop that went OOB couple years ago. Not sure if it was totally made from scratch, or just real obscure brand. Been trying to find it through Google, but no dice. It was full-size tower, looked to be ATX. Had sturdy steel chassis with aluminum panels. Anyone know of any brand/model number that fits the bill?

I doubt it would have been made from scratch as a one-off.

There are many things to consider in designing a PC case including but not limited to form factor mounting, external slots, internal slots, fans, switches, leds, thermal airflow, power supply mounting, EMI compliance, price point (material quality), and the list goes on.

There should be plenty of cases available (whether or not they are asthetically what you are after), what sort of places have you tried?
