Thanks, all.
I like to think I have pretty good Treasure Hunting Skills...

I regularly hit all the usual suspect stores - thrift, craft, discount, hobby, hardware, fabric, etc. And flea markets and garage sales (aka boot sales) in season.
Will have to cruise the cabinet aisle at lowes or home depot next time I'm there. I could use some clunky, bulky furniture, consoles, etc.; gotta have something with dials and lights for the minions to stand in front of and endlessly monitor...
Already tweaking the lab pieces shown above... Need more cables, tubes, wiring, and maybe some control wheels or large dials. And a Big Red Switch...
