I won't do your work for you, you can find all form factors conveniently located in one single page over at wikipedia; a simple comparison between said table and the board dimensions (as listed under 'specifications' in their official page) should answer that.
As to cases, depends.. SSI-EEB (your usual dual socket board) is easier. What EVGA once branded XL-ATX (and has since remained as a 'spec') is much harder.
You can of course have a look yourself for either scenario, but.. much as i hate to recommend anything Thermaltake.. a W/WP-100 or a W/WP-200 is a good choice; not very expensive for its size, fits all and with space to spare.
- for XL-ATXL: If Thermaltake is a no for some reason? There are precious few (and far more expensive) cases that can also really fit everything, but you'd only be paying extra for the bling. See certain older dual chamber Lian Li ones and some InWin ones to get an understanding of the price-tag we're talking about.
- for SSI-EEB (and the reason i'm not recommending one): There are some good ones, but most are older models, so availability is an additional factor; there are even fewer newer ones, but following the retardo-ed trends of millennials today, their focus isn't on superior airflow as much as RGB and nice glass panels so you may stiffle your intake even further! How awesome, i know. Your Corsair 10000000GTI-D-Turbo also fits in this category, money for nothing, glass for free. From all these, precious few are made with true dual socket boards in mind; at worst, they expect two rather than three active coolers inside and are typically made to accommodate just that; this is for air cooling specifically mind you, like you asked for. The Corsair case is meant for dual systems and custom loops (plus bling).
If you're serious about this, go the W/WP 100 or 200 way and call it a day, nice and easy.
Pride, honour and purity.
