For computation sake I would need something fairly fast. The Odroid-C2 looks pretty good. With a Mali 450 GPU I can use Open-CL to speed up a lot of calculations. GPU is very good for processing big data sets like a lidar point cloud. It's CPU is 2ghz quadcore too, which is an improvement over the Raspberry Pi 3. I'll no doubt be able to find suitable hardware if I did go ahead with this, just wondering if its worth the fuss
