We started our render farm tests with giant enterprise servers, which took up a lot of space in our studio and had us all sweating at about 10 degrees higher than the normal room temperature would have been! Fast-forward through a few iterations of our hardware, and we ended up with a design based on cyrptocurrency mining rigs! These compact rigs are fairly energy efficient and take up minimal studio space. We pack ours with six speedy graphics cards to really pump out the frames of our cartoons! And – bonus – they can mine some Ether while they’re off duty!
