Honestly get a RPI and you will be so thankful. You don't need a ton of power off a machine and could save your laptop some stress of really hot.. that does not sound good.
But you could even use minera on RPI. For a little investment your power cost vs a laptop will be decent. And RPI's are pretty cheap. I highly suggest getting one vs your laptop.
And very cool to see the pod in the works. Thanks for keeping us in the loop I love watching your dev process.
I have an RPi B+ and I got the minera RPi image from the support page here and had it all setup, but it wouldn't work with my 3.0 hubs. Before I could get my hands on a 2.0 hub to act as the middle man, my son got a gopro for christmas and I sacrificed my only microsd from the pi so he could use the camera. I just ordered a new bigger microsd and will set it all up again when it comes in. I already have a subdomain forwarded to the lightppd server on my laptop so I can just browse to the minera page from anywhere, I'm going to set the RPi up the same way.
I don't think the laptop is really stressed, All it does is run Ubuntu 14.04 LTS and minera. Not nearly as much as when it had windows 7. It's got an Core i7-2640M / Radeon HD 6630M and 8 GB of Ram. But all that is crammed into a really flat case. I don't know how they got a fan in there but it's got a really powerful/loud when it gets real hot. It sits on its dock all the time and that has some warmth of it's own as well that contributes to the overall temp. The area near my desk stays relatively warm with the laptop, two desktops, and the 12 miners all going pretty much 24/7
