I just bought this new AOpen H600A case. I also bought a Coolermaster 80mm fan with heat sensor. I have sucessfully fitted this in the front "chassis fan" space between the 3.5" bays. I just wondered, the case did not come with an optional fan holder/cage, thus the fan is installed but open to anything that could get caught in it. Do i preferably either need to get a 'fan guard' like this or see about getting the optional fan holder/cage? I think ideally the answer is the 'fan guard' and when I get a new 80mm fan for the back of the case in addition to the one that was pre-installed by AOpen, I could think about getting one like this from Enermax here - here that is already fan guarded up as it were.
