BigBen

Hi all! I apologize in advance if this has been asked and answered elsewhere. I'm getting ready to start my first build with this FE, and I'm trying to figure out how much drive space I'll need. I'm only going to be emulating MAME and consoles up to probably PS1. I'm not concerned about the ROMS, I know they don't take up a whole lot, but what about the art/movies, bezels, etc? is 2TB enough? 4? Thanks in advance!
