L shaped desk under $100 with a platform to put PC under desk

My current desk is super unstable so I’m search of a new one. It’s also really crowded because I have my PC on top of my desk along with my 2 24” monitors making the desk really crowded. I would ideally like a desk that is around 50-60” because my current one is 47” and I feel like it would be better if I just had a bigger one.
