Identifying Loose Components After PC Cleaning: Need Your Expertise!

Hello esteemed readers,

I recently engaged in the process of cleaning my personal computer and, after carefully disassembling it, the reassembly went quite smoothly. However, I encountered an unexpected dilemma: I found myself left with two mysterious parts and two screws. Regrettably, I cannot recall their original placement or purpose within my setup.

I’m reaching out to the community for assistance in identifying these components and providing guidance on how to reattach them properly. To facilitate this, I have included images of my PC’s interior in slides 2 and 3, which may help offer context for the inquiry.

If you possess any insights or expertise regarding these pieces, your assistance would be immensely appreciated. Thank you in advance for your time and help!
