you can take to most of the LFS and they can drill it for you i know Gabe does, i would go with a fuge you can use the ac70 torun other media like carbon or chemi pure elite since your going to have a small fuge or for emergencies to run more carbon. dont worry keep asking questions that way you run into less problems later. you dont need a vortech on that size tank i would run 2 of the new nano koralias (425gph)on a wave maker or the the 2x750gh on like the jbj wave maker save money for other things. also with a fuge you can run a skimmer in there.
