You've selected a uatx motherboard. Most cases will support them but typically they are used for small builds in cube towers for example. Since you've selected a mid tower, and as far as I can remember the H24 supports the ATX form factor, I'd recommend getting a bigger ATX mb. It will fit the case better, you will have less chance of running into heat issues and assembly will be easier.
EDIT: Quick question, is the 1000 dollars you have now your max budget or are you able/willing to spend more? If so, how much? Also, what are you planning on doing? Video games? Maybe rendering, streaming?
