This is a video of me trying to turn it on

No ram/faulty ram?
Ram must be on pairs

Does power LED light or flash? Beep code sounds like "no ram" signal, but it seems a bit too short.

Sounds like a RAM issue. Try pulling all but one pair and see if it starts up.

Also, any activity from the white power LED above the power button while this is going on?

Also, are you trying to start it up without the air deflector? I can't see it well in the video. That could explain the red light at startup and the fans, but not the "beep", that probably is just a RAM issue. Either bad modules or slots. Try changing the RAM from one slot to another, (always in matched pairs) and/or buying new modules.
