Some of you might have noticed that our mid-review video showed our rover with a laptop strapped to the chassis with a bungee cord. We were temporarily using that machine, borrowed from one of our Pioneers, while we figured out our computing needs for the rover. We decided to build our own computer, using a Pelican case to seal it from the elements. (Don't worry -- we have fans with filters for our cooling needs.) Our parts arrived yesterday, and we've been assembling the computer.
