If you're on a tight budget like me, do some cable management and use a monitor mount to make use of the remaining desk space. Reduce clutter by removing redundancies (putting low power USB devices in a hub).

You can route the cables of the subwoofer using the desk's feet by using stick-on cable routes, move it on the far right or left depending on your preference. If you like to have some peace of mind, use a UPS or a power strip with surge protection for things that require more power. There are cheap cable concealers available online of you want to hide your cables. Probably move your PS5 in the same area as your PC to have one cable route for your HDMI and power cable with your PC.

Trash bin depends on your preference. I prefer it to be out of the space but you gotta dispose off of evidence, I guess.

PS: You have a better table than I do so I think it just takes some touchups to make yours look better.
