I don't mean to burst anyone's bubble, but why go through the work of setting up a snow golem thing when you can just set up a pump->compressor->compressor->reactor? From the wiki " As of v1.337 a pump with a infinite water source under it and a compressor placed directly next to it will pump and compress water into snowballs without the need for cells." This means once the snow is made from the pump and compressor you can just follow the same process as before without the snow golem variable. Just seems simpler and a little more realistic for those who like to play like that (like me).
