Oh I didn't realize that it didn't have integrated graphics.. does it matter than the ones you suggested say micro ATX?
Only if you need the extra expansion slots that come with a full ATX motherboard.
Micro ATX motherboards are compatible with full-size ATX cases. If you put a micro ATX motherboard in a case that is designed for a full ATX motherboard, there will be some unused space inside the case at the bottom (for a tower case) or on the left (for a desktop case). This can actually make it easier to get things set up, since you've got more room to work inside the case when connecting up front panel USB cables, power/reset button, etc... or you can go with a smaller case if you want a system that takes up less space overall.
If the world isn't making sense to you, you're either drinking too much or not drinking enough.
