I wouldn't worry too much about customer support when it comes to cases, as there's not really much that can go wrong. Both cases have glowing reviews, are huge and, after double-checking, both support XL-ATX. You can see for yourself here: http://www.nzxt.com/product/detail/111-switch-810-case.html

Click 'SPEC' then scroll down to motherboard support.
Best bet, Go with the NZXT Phantom 410: http://www.newegg.com/Product/Product.aspx?Item=N82E16811146087
And it is an instant $10.00 save and comes with a $20.00 mail in rebate making it $69.99. and even without the saviings it is the best case you could get under $100.
