@joshua,phantom is one of my favorite case,moto is a cable management geek so keep it tidy
and i won't suggest level 10 GT because-
recently saw it on a nearby shop and the things that i noticed:
great build quality and looks,the case is sturdy and looks bad as hell.
color changer fans look cool and suck plenty of air.
good cable management and can fit large graphic card(s)
roomy enough to fit a high end *air cooled* system.
hot swap drives,headphone holder and other stuff is common now days but still looks cool.
expensive and not worth a $300 price tag(you can it cheaper may be $290 or so)
looks big,very heavy, but still not enough room to fit a heavy watercooling loop.the best you can do without cutting your case is-
there are a lot of other cases that are cheaper and provide similar(or better) features.
side window is too small to show off things.
bottom line don't get level 10 GT unless it's a personal preference because you can get the same features for less.
good luck with your choice
