Just one tiny screw

I'm having the hardest time (ahem) trying to open this ancient desktop PC.  It's been trusty over the years but it's been gathering dust for a while.  I remember getting the PC at Costco when I arrived off the banana boat.  I even had to borrow a friend's Subaru Outback because I couldn't fit everything in the backseat of my car.

I just need to remove the hard drive because it has my oh so secret data.  What were my playlists?  What e-books did I read or ignore?  What about all that email sent to people I haven't heard from in.........[cricket noises]......years?   To complicate matters, I opened my tiny PC tool kit and it literally has cobwebs.   Dirt and dust and lord knows what else.  

I've never been one of those people who got excited over taking apart a PC or replacing a car tail light.  I find more excitement from cooking Spanish rice.  The dirt and dust and cheap sheet metal proves that I lived in the crypt, right?
