I'm planning to get intake and exhaust fan to put at the rear and front of the casing as you can see at the picture at the place where I circled red, do you think it will fit?

just send to uncle ianho, he will figure it up for u....

bro..plz resize those images before post it..

ur AMD system i thnk no need that good airflow as ur 5200 GC also no generate heat also

its 7300GS, erm, just want to add fans for fun as I plan to slightly OC a little bit

I have the same casing in my room.
Originally, there should be a bracket to hold the fans, you put the fan in the plastic bracket, then put the bracket on the casing, the brakcet will be automatically locked to the casing with it's plastic hooks.

Where's the white bracket for you're casing?
