Help with future tank purchase

[jb0187]

Well guys I need some help figuring out how many holes should I drill on a new tank I'm buying the measurements are 96x24x31 tall. I have a 75 tank now but I don't want to have a internal overflow anymore I would like to have an external one so I figure I ask you guys what are your thoughts on how many holes I need to have for the water going in and out of the tank Thanks
