They did install one stock fan and one non-stock fan. Also the standoffs came in at the end I think.
Right, must've forgot about it. Anyway my point was it would suck if you installed the mobo then had to take it out to make it easier to install a new back plate for your CPU fan.
Also make sure you put the stand offs in the right holes, your case will come with an instruction booklet that tells you where to put them for your mobo type.
