I'm doing well, at least by my standards and lack of skill.

However, I learned a lesson. Cordless drills are good only for small jobs. The drill battery quit on me on my very last hole. I would have finished and saved myself at least an hour. Oh well.

I think it looks ok. There was only one burr which I ad to file off, and the hole was a tiny bit irregular but it looks presentable.

CyberDruid, kudos to you for recommending going the opposite direction on the holesaw. It took a bit longer, but patience and slow drilling was the key. It also helped that the drill I have is wimpy (Ryobi 9.6 volts), which meant that I had zero problems keeping it relatively steady.

I couldn't find a decent piece of wood, and I figured the wife wouldn't appreciate me using the kitchen cutting board lol

In the end, the job went well even without a sturdy piece of wood. I had something behind, but it kept shifting, so it might as well not have been there. The Lian Li aluminum is not as wimpy as I thought and the mobo tray didn't bend in the least bit. I need to finish up, clean up the mess I made and mount the mobo.
