You take the lid off the box, and right away it feels different. The Argon ONE V3 isn’t trying to look flashy—it’s trying to solve problems. It’s heavier than most Pi cases, cool to the touch, and feels like it could survive a drop off the workbench (though hopefully it won’t have to). I had it on my table just last week, helping a client build a compact home server setup with native NVMe boot. Things got interesting fast.

If you’re into Raspberry Pi 5 projects and you care about speed, thermal performance, or just keeping things tidy with an all-in-one case, this guide is for you. I’ll walk you through everything—how to prep your board, connect the NVMe SSD, tune the fan, and get the system booting from your drive like a mini workstation. Whether you’re a maker, a product reseller, or an OEM buyer looking to scale, this case has something to offer. Let’s get started.

Argon ONE V3 M.2 NVMe PCIe Case at a Glance

Key hardware features & specs

• CNC-milled aluminum shell with integrated heatsink fins

• PCIe 2.0 x1 M.2 key-M slot (2230/2242/2260/2280)

• Dual full-size HDMI, USB-C power passthrough, power button & IR receiver

• Active cooling: 30 mm PWM fan, magnetic top cover

What’s new vs. V2

Unboxing checklist

1. Main case body & top lid

2. HDMI-power board with pogo pins

3. Thermal pads (CPU + PMIC)

4. Screws × 6, rubber feet × 4

5. Quick-start leaflet

That’s the hardware snapshot. Now let’s prep your Pi so nothing blindsides us later.

Preparing Your Raspberry Pi 5 for the Case

Required firmware & bootloader

Make sure your Pi 5 EEPROM is dated 2024-03-14 or newer. An older build may refuse to enumerate the NVMe link.

Choosing a compatible NVMe SSD

Tip I avoid DRAM-less drives bigger than 1 TB; the Pi’s single PCIe lane becomes a bottleneck anyway.

Power supply & cables

• USB-C PD 5 V / 5 A brick recommended.

• Use a 30 AWG or thicker USB-C cable ≤ 1 m.

• If you chain peripherals, budget an extra 1 A headroom.

A solid foundation built—time to grab that mini Phillips and dive in.

Step-by-Step Hardware Assembly

Installing thermal pads, heatsink, and top shell

1. Peel the blue film off the graphite pad.

2. Center it over the CPU; align the smaller pad with the PMIC.

3. Lower the aluminum shell—gravity does the pressing.

Mounting the Pi 5 to the HDMI-power board

Four standoffs, finger-tight first, then an extra quarter-turn. Over-torque cracks traces; I learned that lesson on a late night build for a client demo.

Seating and securing the NVMe drive

Slide at 30°, press flat, and lock with the tiny screw supplied.\
If the PCB flexes, add the included spacer under the tail.

Closing the enclosure & final checks

Before the lid snaps on:

• Fan cable clipped?

• Pogo pins aligned?

• GPIO ribbon clear?

Transitional tease (32 words): The lid clicks shut, but the real magic happens when electrons flow—let’s power up and teach the firmware some new tricks.

First Boot & System Configuration

Updating EEPROM & enabling PCIe/NVMe

sudo apt update && sudo apt full-upgrade
sudo rpi-eeprom-update -a

Reboot, then confirm:

vcgencmd bootloader_version

Editing config.txt for PCIe lanes

Add:

dtparam=pciex1

Optional but wise:

dtparam=pciex1_gen=2

Verifying NVMe detection

ls /dev | grep nvme
sudo hdparm -I /dev/nvme0 | head

If you see “missing opcode” warnings, double-check the SSD’s firmware.

Firmware’s happy? Good. Let’s give the drive an operating system to chew on.

Installing the Operating System on NVMe

Flashing with Raspberry Pi Imager

1. Pick Raspberry Pi OS 64-bit.

2. Under Storage, select the NVMe (not the micro-SD).

3. Enable SSH and set hostname while you’re there.

Migrating an existing micro-SD install

sudo rpi-clone -f -e sda nvme0n1

Pull the SD; the board should boot from NVMe automatically.

Testing boot speed & reliability

Those numbers usually grab attention during customer demos—speeds and feeds never get old.

Managing Fan, Power Button & IR Features

Running the setup script

curl https://download.argon40.com/argon1.sh | bash

It drops a service into /etc/systemd/ and a config at /etc/argononed.conf.

Customizing fan curves

Default table:

I bump the first trigger to 50 °C in warm offices.

Mapping the power button & IR

• Short press: graceful shutdown

• Double tap: reboot

• Hold 3 s: forced off

IR codes sit in argon1-ir.conf. I once mapped mine to the mute key of a spare TV remote—lazy, yes, but effective during presentations.

A cool board is a happy board, yet numbers tell the story best—let’s benchmark.

Performance & Thermal Benchmarks

SSD read/write vs. USB 3

CPU temps

Real-world gains

• Nextcloud page loads: 1.8× faster

• 4K Plex transcode: plays smooth, no dropped frames

• LibreOffice launch: 3.5 s vs. 8.9 s

Benchmark charts look great on slides, but what if things go sideways?

Troubleshooting & FAQs

NVMe not detected

• Reseat the drive; ensure standoff matches length.

• Check pcie_aspm=off in cmdline.txt for picky controllers.

HDMI board alignment

If one HDMI port blacks out, loosen the four mount screws, reseat, tighten diagonally.

Fan noise

A whine at low RPM often means loose top lid; a tiny dab of silicone pad under the magnet cures resonance.

Boot-loop after EEPROM update

Hold the power button 15 s to clear BOOT_ORDER. Re-flash a known-good EEPROM via SD recovery.

A fix in the field often seals a customer relationship. But why stop at fixing? Let’s talk tailoring.

Customization Tips for OEM / ODM & Wholesale Buyers

Adding logos or accents

• Laser engraving: matte silver, 0.05 mm depth—works on small runs.

• Silk-screen: full-color, needs 300-piece MOQ.

• Anodized color lid: black, space gray, or custom Pantone.

Bulk packaging & bundles

MOQ, lead-time, QC

• Standard MOQ: 200 units

• Sample lead-time: 7 days

• Mass production: 18–22 days with 100% functional test & 10% burn-in

Customization talks often spark bigger ideas—clusters, camera rigs, even car dashboards.
