I did some TLC on my PC today, specifically targeted PCBs such as my motherboard, GPU, and my Wi-Fi & sound cards. They were dusty but luckily a blast of air managed to get the best of dust off.

Additional PCIE devices are one of my favorite things about desktop PCs becauase they're basically unlimited in their potential in terms of customisability and expansion. A small feature in the grand scheme of things, but these small details in desktop PCs is what I value over something like a gaming laptop.
