Fan Layout Helper

Please view attachment for full size; the preview image doesn't do it justice :P

Inspiration:
So I've been building a PC in the last few days and this is the first time I took it seriously, so I thought I'd give proper airflow management a go.

Little did I know there was a lot to learn...calculating different pressure setups, Fan CFM, fan sizes, PWM hubs, intake/exhaust etc.

I did get there in the end, but if there was an app that could've figured out an optimal layout based on some parameters I set, I would've been able to build my PC a lot faster.

So here it is: the UI for a (fictional) app/SaaS service that can figure out the whole thing for you!
