Nzxt h440 mid-tower black/red gaming case


i see that this case is suggested to not have a cd drive. how would this work? never used a pc without a cd drive.

can you buy a usb cd drive? if so would you be able to completely reinstall windows with a usb cd drive?

can you use a usb stick to install windows or reinstall windows?

i am asking because this is going to be my next case unless something else that looks better comes out when i build/buy.
