Have you lifted a rig with 4x GPU cards before? It's not something you want to take on the train with you during the commute.
It's not just the weight. Someone might call the bomb squad.
Yeah, once they see all of the led-lights, cables everywhere, and really loud fans going they're sure to notice the "convenient and portable work-briefcase-mining-rig with 4x 6990s". It's a bomb, run!
I was also planning to add a car battery (to make it portable) so I can move it around the office with me. Rolling work bags are all the rage right now. LOL!
You guys are great, thanks for all the awesome ideas!
