Will the Intel DZ87KLT-75K Motherboard fit into the Corsair CC-9011017-WW Case? To me it seems by reading the documentation that the motherboard is too big, but I'm not sure as I have no experience with this and I was told that all ATX motehrboards are compatible with all ATX cases.
From the links you provided:
Intel DZ87KLT-75K Motherboard Form factor: ATX
Corsair CC-9011017-WW Chassis Compatibility: ATX and Micro ATX motherboards
Since they both conform to the ATX form factor, then they should be compatible.
When putting ATX boards into an ATX chassis, the only gotchas tend to be when it comes to motherboard component placement and various over-hangs within the chassis itself (like drive cages banging into full length video adapters for example).
