i'd definately consider anywhere where returns are easy.
from experience,
cases come with very little padding.
and those ups or fedex guys are not too kind when it comes to large boxes light enough to throw as they please.
while the rest of the case is made out of metal... so it's okay to take the damage,
the PSU and plastic front cover isn't.
i've ordered many cases. but about 30% of them come with boxes all destroyed.
i had to return 2 so far.
so make sure you order from places where returns are easy. or places where they'll double box.
i'd recommend newegg... for easy returns.
