If you can get the 300 for $35+4+4 then that's a good deal. Microcenter always has a lot of good deals.
The usual price for the 300 is $60+more for 2 fans if you want, while the usual price is $70 for the illusion. However, the illusion goes on sale like once a month for $45, that is really the only good time to buy it. Otherwise there are better cases at the $60-70 range that offer cable management and a bottom vent for the psu.
+4+4 like a total of 8 fans ?
