Who it fits

Key specs explained for this unit

Intel J4105 Processor

This quad-core chip runs up to 2.5GHz and uses only 10 watts of power. The low thermal design power means it generates little heat, which supports the fanless design. You get stable performance for routing tasks without noise. This is ideal for users who need quiet, energy-efficient operation for home or office network gateways.

4 x Intel 2.5GbE Ports

The device includes four dedicated Ethernet ports supporting 2.5 gigabits per second. This allows for faster internal network traffic compared to standard 1GbE connections. You can connect multiple high-speed devices or create robust routing paths. This spec is crucial for users managing heavy data loads or those upgrading their local area network infrastructure.

Fanless Design

The unit relies on an aluminum alloy shell for heat dissipation instead of fans. This eliminates moving parts, resulting in zero noise and higher reliability over time. It supports continuous 24/7 operation in various temperatures. You benefit from a silent environment, making it suitable for living rooms or quiet offices where noise is a concern.

0G RAM / 0GB Storage

The listing provides the base unit without installed memory or storage. You must purchase and install DDR4 RAM and an mSATA SSD separately. This allows you to customize capacity up to 16GB RAM and 512GB storage. It suits technical users who want to choose specific components for their firewall or router software needs.

Design and build overview

The Sharevdi firewall mini PC uses an aluminum alloy shell for its chassis. This material choice supports the fanless design by acting as a heat sink. The listing states the unit withstands temperatures up to 60°C. This means you can place it in enclosed spaces without worrying about overheating. The 10W TDP processor generates minimal heat, allowing passive cooling to remain effective during continuous operation.

According to the listing, the physical dimensions are 4.98 inches wide, 2.17 inches high, and 6.99 inches long. The weight is listed as 3.66 pounds. These measurements indicate a compact footprint that fits easily into tight network racks or behind monitors. The listing also mentions a VESA mount is included. This feature allows you to install the micro PC directly behind a display to save desk space.

The rear panel layout includes four Intel 2.5GbE LAN ports, two USB 3.0 ports, one VGA port, one HD port, and one DC power input. There are no front-facing controls or buttons visible in the specifications. This clean exterior reinforces its role as a dedicated appliance rather than a general-purpose computer. You will need to access the ports from the back, which requires careful cable management in confined areas. The black finish is standard for equipment that sits in server racks or utility closets.

Setup steps and daily operation

Setting up this unit requires you to handle several hardware and software steps before it can route traffic. The listing specifies that the device ships with zero gigabytes of installed RAM and zero gigabytes of storage. You must purchase and install compatible DDR4 memory modules and an mSATA SSD yourself. The maximum supported memory is 16GB, and storage can expand up to 512GB. Hard disk drives are not supported. You also need to install an operating system. The product page notes it has been tested with pfSense, Linux, and Ubuntu, but no OS is pre-installed. You will need to create bootable media and configure the software to utilize the four Intel 2.5GbE LAN ports effectively.

In daily use, the fanless aluminum chassis ensures silent operation. The 10W TDP allows for continuous 24/7 runtime without noise. You can mount the unit behind a monitor using the included VESA mount, saving desk space. The compact dimensions help keep your network setup tidy. You get two USB 3.0 ports for peripheral connections and video outputs via VGA and HDMI. The AES-NI support in the J4105 processor helps accelerate encryption tasks for firewall duties. You should monitor internal temperatures, as the passive cooling relies on the case to dissipate heat up to 60°C. This setup is ideal if you prefer building your own network appliance from scratch rather than buying a pre-configured router.

What You Need To Know Before Buying

Owning this unit requires you to treat it as a bare-bones networking appliance rather than a ready-to-use computer. Since the listing specifies zero gigabytes of installed RAM and zero gigabytes of storage, you must source compatible DDR4 memory modules and an mSATA SSD separately. You will also need to install a supported operating system, such as pfSense or Ubuntu, as no OS is pre-installed. The fanless design relies on passive cooling through the aluminum chassis, so ensure you have adequate ventilation space around the unit to maintain stability. This device fits best into a setup where you need dedicated 2.5GbE routing capabilities without noise. It complements other Mini PCs by handling network traffic while your primary desktop manages daily tasks. Check that your existing network infrastructure supports 2.5GbE speeds to fully utilize the four Intel I226-V ports.

Check before you buy

• Purchase compatible DDR4 RAM and mSATA SSD separately
• Verify your network supports 2.5GbE speeds
• Prepare to install a supported operating system
• Ensure adequate ventilation for passive cooling
