Newbie questions on mining rig

i am a complete newbie on coins & mining. reached here through a post on a hacking subreddit and whole idea seems interesting. being fortunate with free data & electricity i am thinking of building a small single card rig.

i travel frequently so unfortunately am stuck with a mini-atx case (silverstone sst-ml07b milo). 1070 in my area cost ~USD 468 & 1080ti USD ~844. which card would you recommend from these two? is extra $ for 1080ti really worth it in the long run? is 10 mbps broadband enough? do i need some kind of gpu cooling kit ? if so please recommend one.
