First thing’s gotta be a case that screams “dead‑nightmare.” Think dark, matte black, with a big window that looks like a cracked skull or a cemetery gate, and a set of RGB lights that flicker like dying fireflies. Then crank up the airflow so the heat doesn’t turn the rig into a soup—nothing worse than a zombie turning a gamer into a steaming pile of pixels. That’s the only feature that can keep you alive while you’re hunting for the next blood‑curdling title.
