Best Raspberry Pi 4 Cases of 2026

There is no fan in the P173, and that is the design: the case is the cooler. It's a 174-gram block of aluminum measuring 90 by 65 by 33 mm, with four pillars that press onto the Pi's chips through the supplied thermal pads, plus a copper shim for the CPU in place of a pad. More metal in contact with the board means more heat leaving it.

That makes it the case we choose for a Pi meant to be forgotten about: a Pi-hole, a Home Assistant hub, a media box that runs all day. Nothing spins, nothing whines, there's no bearing to wear out and no fan to collect dust. The board warms the metal, the metal sheds it into the room, and you never hear about it.

Passive has a ceiling worth knowing about. There's no fan mount, so you can't add airflow later, and a Pi 4 held at full load for hours will run warmer here than in one of the actively cooled cases — normal server duty sits well inside that limit. Assembly is a handful of screws, and the SD card and the GPIO ribbon slot stay reachable, which matters more than it sounds when you're reflashing cards every week.

The box holds more than the price suggests: a 40 mm fan, four aluminum heatsinks, screws, rubber feet, a screwdriver and a snap-on lid that comes off for GPIO access without lifting the board out. The ABS shell weighs 70 grams, and the cutouts for USB-C, micro-HDMI, USB and Ethernet line up cleanly on a Pi 4.

Where you plug the fan in decides how the whole thing feels. On the 5V pin it moves plenty of air and makes itself heard; on 3.3V it fades into the background and still holds a normal desktop or media-center load. Moving that wire from 5V to 3.3V is the single change that makes this case livable in a room where people are trying to think.

For a first build, a classroom set or a Pi that lives on a shelf, this is the case we hand people. It covers cooling and protection with nothing else to buy, it goes together in minutes, and it moves considerably more air than the passive aluminum pick above for the same money.

It reads as a small desktop computer rather than a Pi in a box: matte black aluminum on the body, a clear acrylic cover on top, and a light strip down one side that cycles through colors. There's a brightness control for the lighting, which matters more than it sounds — turned down, it's a glow rather than a lamp lighting the wall behind your monitor.

Cooling gets more room than a flat case allows. A large heatsink sits over the CPU and a fan at the base pushes air up through the tower, so the whole thing works like a chimney with a Pi at the bottom of it. Running an emulator front end for an evening, the board stayed comfortably cool and never reached the point where a Pi 4 starts slowing itself down.

The fan is the part to get right. Its exhale direction matters — fitted the wrong way round, the blades foul the housing and the noise gets noticeably worse, so check the diagram in the manual before you close the case up. Even mounted correctly, it's a fan you hear when the Pi is working hard; the Geekworm is the one to pick if silence matters more than looks.

Which is the honest framing: the Argon ONE V2 above does more for less money — rear-routed ports, full-size HDMI, a power button — and this one earns its place on appearance rather than features. If the Pi sits where you'll actually look at it, that's a fair trade; in a cupboard, it isn't.

The reason to pick this over the other clear acrylic cases is in the box: a 5V 3A USB-C power supply with an on/off switch, so a bare board becomes a working Pi without a second order. The switch is the quietly useful part — you cut power at the adapter instead of fumbling for the cable — and it's listed as ETL certified, which you don't get on every bundled charger.

Around the board it's the familiar acrylic sandwich: clear plates, a 30 mm fan, four heatsinks and rubber feet, with the board visible through the shell so you can see the activity LED from across the desk. Wire the fan to 3.3V rather than 5V and it disappears into the background while the heatsinks carry most of the cooling.

The lid is the whole idea. It slides off magnetically in about a second, exposing the GPIO header, the camera and display connectors and room for a HAT, then goes back on just as quickly — no screws, no clips, nothing to lose in the carpet.

That makes it the case we keep coming back to for a bench Pi, the one that's a work in progress: a sensor on the header this week, a ribbon cable to a camera the next. It's also the slimmest aluminum option here, and the anodized space grey finish looks like it belongs next to a monitor rather than under a desk.

Cooling is passive and leans on the shell: the aluminum body and the supplied thermal pads draw heat off the board, with no vent openings to help it escape. That's fine for a desktop, a Pi-hole or a light Home Assistant box, and less fine for a Pi pinned at full load for hours. Argon's Fan HAT fits if you decide you want active cooling later, which softens that ceiling considerably.

It's a grey NES-shaped box that turns a Pi 4 into something worth putting under a television. The kit includes the shell, a 35 mm fan, four heatsinks and a screwdriver, and the fan is mounted to pull air sideways across the board rather than straight down onto it.

Fit is what makes or breaks a novelty case, and the cutouts here line up: the USB, Ethernet and micro-HDMI openings sit where the board puts them, and the Pi drops in without forcing anything. The fan moves enough air that the shell stays cool through a gaming session, and the whole thing sits flat and stable on a TV stand.

This is the one we point at when someone is building a RetroPie box for the living room: it cools properly, it costs about what a plain ABS case costs, and it looks like the console it's imitating. One thing to know before you order — the buttons on the front are decoration, and the version with working controllers is a separate listing.
