I also highly recommend adding a second fan in parallel to the first (as a pre-accelerator) which could be useful for supplying sufficient airflow to your G-suit. Although this may overload your computer, it could be a bonus, giving a realistic "smoke and fumes in the cockpit" emergency scenario. Best then to relocate the computer next to your window. Keep your window open, regardless of the loss of pressurisation that this will result in. But be aware that flying during big thunderstorms, your monitor may get wet, and you also risk the chance of lightning strike. Turn the Brightness control way, way up, and make sure your CPU is earthed. I don't know if leather flying gloves will stop your fingers being fused to your joystick (cow's get fried when hit by lighning don't they?) so consider the use of some rubber gloves. Also be aware of the risk of birdstrike, so keep both of your helmet visors down. Last but not least - don't drink and fly.
