Which “boring”upgrade quietly changed how you use your computers?

I do a mix of creative work and general tinkering at home, and the biggest changes for me weren’t new cameras or a new PC, but the “infrastructure” around them.

In rough order:

• Swapping random dongles for a solid USB-C dock
• Adding a second monitor(LG) so I’m not editing on a 13"" screen
• Using a portable SSD(samsung T7) as my “current projects” drive
• Adding a small 2-bay NAS (DH2300) so old RAWs/exports live off the laptop and I can pull them from my desktop, couch, or TV

Individually they’re small, but together they killed a lot of friction: less cable chaos, simpler backups, and no more hunting through random drives.

What “boring” upgrade (NAS, UPS, 10GbE, better Wi-Fi, KVM, server closet, etc.) ended up changing your day-to-day the most, even if it didn’t look exciting on paper?
