I know the culprit is either my hard drive or my front case fans. I don't know how to proceed from here, but I backed my hard drive up already.
This morning I turned it on and there was a very audible humming sound from my PC. It didn't sound terrible, it was a lot like the sound an old fashioned desk or ceiling fan would make. It did sound like it was coming from the front of my PC, where the hard drive cage and two intake fans are located.
I panicked and backed up the hard drive. I took off the side panel, and the shock from that seems to have stopped the buzzing sound. Not sure how concerned I should be right now.
