I have a limited space in my room, the only space for my pc is on top of a custom desk built into the wall of the room which means it's right side (facing out) of the pc is right next to the wall with less than 1cm space in between. My current dell e521 has large vents on the front and back only, airflow is good for this type of positioning. However, I am planning on getting a new pc soon and all the case options have vents on the right side as well as the rear for the exiting airflow.
I'm concerned the right side vents opening right into the wall will affect the airflow in a negative way. I'm wondering if it's better to block these and just allow the airflow to exit the computer towards the rear where there is four inches of space between the back of the computer and the wall.
Also,I have the option to choose a coolermaster 343 and 344 which are both 7.2'' wide, and some other brands which are slightly smaller at around 6.8'' wide, there is even a coolermaster 361 which is 5.9'' wide. It makes every bit of sense to maximise the limited amount of desk space I have so I would like to go with a slimmer case but I'm not sure if slimmer cases are better or worse with regard to airflow, especially with the type of positioning I have with one side blocked off.
