Creating my first Pc on pcpartpicker.com: parts compatability

[Richardw63]

I have all my parts picked out and it says they are all compatible but i get a note at the bottom that says:
"Asus P8B75-M/CSM Micro ATX LGA1155 Motherboard has an onboard USB 3.0 header, but the Cooler Master HAF 912 ATX Mid Tower Case does not have front panel USB 3.0 ports."
Here is my build: http://pcpartpicker.com/p/2JMVL
Will this affect much? if yes can you recommend a different mid tower case compatible with Usb 3.0 close to the same cost as my current case? thank you!
P.s sorry if i sound ignorant because i truly do not know much as this is my first time
