If your weight can afford it, I would recommend getting a used laptop computer (super cheap; maybe add an SSD). The power supply shouldn't be too difficult to figure out, and you'll probably be able to get more processing power. Of course, many teams have had success with Raspberry Pi's and other Linux compatible systems such as ODROID X2s or UDOOs (both have quad cores; worth looking at for vision processing). I can't believe you guys did vision processing your rookie year. You guys must have been pretty dedicated and organized :P
