Better airflow?

Hello, i dont have a gaming case of any good places to let air leave my computer, I had a idea to remove the 2 unused PCI Brackets, And the PCI-E is by the 2 brackets. .So should i remove the 2 unused brackets for better airblow for my GPU? and i wanted to know if its a safety harrased if a little kid decide to stick thier hads into the opened Brackets.

If your worried about children sticking their fingers in the open expansion ports than I would recommend not removing them, the amount of air they would allow in would be negligible at best. Your really best adding a fan to the case if your concerned with ventilation.

you could buy one of these.
