Third, choose layout based on your actual desk life. A 60% board frees mouse space; a TKL keeps arrows and function access; full-size is still nice if you use the numpad daily. If you edit video, work in spreadsheets, or play a lot of RPGs with keybind sprawl, smaller isn't automatically better.
Fourth, treat wireless like a feature with responsibilities. For headsets, 2.4 GHz dongles are usually the low-latency play; Bluetooth is convenience. For keyboards, reliable 2.4 GHz can be great, but wired is still the nothing to troubleshoot on game night option.
Fifth, decide how much software you're willing to tolerate. Some players love profiles and per-game EQ; others want set-and-forget. If you already hate driver popups, don't buy into a setup that requires constant tinkering to feel right.
Picture a weeknight ranked session: you launch your shooter, Discord is active, and you're trying to play seriously without turning your room into a cable nest. A Hall effect keyboard with a sensible actuation setting (not necessarily the lowest) can make strafing corrections feel cleaner. Pair that with a headset whose mic doesn't crumble when teammates overlap, and your comms stop being a liability.
Now add the real-world factor: you play for three hours, your shoulders tense up, and suddenly your aim is worse than your gear ever was. That's where non-sexy purchases like gaming chairs and simple ergonomics matter. You don't need a throne, but you do need a seat that lets you sit neutral, keeps your forearms supported, and doesn't force your neck forward under headset clamp pressure.
