Design and construction quality
The XCY X58's chassis is machined entirely from a solid block of extruded aluminum. The entire top cover and sides feature deep fins that act as a giant heatsink to dissipate internal heat.
Holding it in your hand, it conveys a remarkable sense of solidity; there are no creaks, flimsy plastic parts, or openings that allow dust to enter directly.
Weighing 1 kg and measuring 193.9 × 127 × 57.2 mm, it can be easily installed inside an electrical panel, behind a commercial counter, or anchored to a wall using standard brackets.

Screen and multimedia
Since it is a desktop mini PC, its image capabilities depend on its rear outputs:
-
HDMI output: Enables 4K resolutions at 60 Hz with impeccable sharpness for modern monitors or public information panels.
-
VGA output: Very useful in industrial environments for connecting older displays, point-of-sale terminals, or service monitors without active adapters.
-
Analog audio: Incorporates separate 3.5 mm jack connectors for headphones and microphone, offering clean sound without perceptible electrical interference.

Performance and software
Under Windows 11 Pro, web browsing with dozens of tabs, complex spreadsheets, and management software run with complete fluidity. The system includes no unnecessary programs or assembler customization layers; booting is clean and straightforward.
The Intel Core i5-1335U processor handles multitasking with ease thanks to its 10-core hybrid architecture. On Linux distributions like Ubuntu Server and Debian, hardware recognition is immediate, detecting both Realtek network cards without the need to compile external drivers.
The transfer speeds of the included NVMe SSD are in the basic PCIe 3.0/4.0 standard range, easily exceeding 2,000 MB/s in sequential read, which speeds up boot times and loading of local databases.

Energy consumption
Efficiency is one of the device's strongest points:
-
Standby (Idle): Power consumption ranges between 8W and 11W at the plug.
-
Typical office use: Remains stable between 18W and 26W.
-
Maximum continuous load: It has peaks of up to 42 W before stabilizing at around 30 W due to thermal management.
Its compatibility with voltages from 12V to 19V allows you to do without the included wall adapter and connect it directly to industrial DIN rail sources or 12V battery systems in camper vans and isolated solar installations.
Temperature and noise: thermal behavior
Because it has no internal fans, the noise level is 0 decibels. There is no electrical hum or mechanical vibration whatsoever.
Heat dissipation relies entirely on the contact between the processor and the metal chassis. During prolonged synthetic stress tests, the outer casing reached touch temperatures between 48°C and 54°C. This demonstrates that the chassis performs its heat dissipation function, although it requires placing the system in a location with basic natural ventilation, avoiding enclosed cases without airflow.
Connectivity and extras

Front panel: control, peripherals and power
The front panel houses the device's 8 USB ports, DB9 serial communications, and power button:
| Connector / Element | Amount | Type and specifications |

Explanation of the gold-plated connectors (SMA): Wi-Fi, Bluetooth, or 4G LTE
Because it has a sealed, solid aluminum chassis that would block any wireless signals if the antennas were internal, the manufacturer installs two female SMA coaxial connectors on the back. Their exact function depends on how you configure the device.
-
Factory-installed Wi-Fi and Bluetooth: In versions purchased with RAM and an SSD, the computer includes a pre-installed combined wireless card in its internal Mini PCIe slot. The two gold-plated connectors connect to two adjustable rod antennas (included in the package) to provide Wi-Fi coverage and Bluetooth connectivity.
-
4G LTE Modem Mode: If you purchase the barebone version or decide to replace the Wi-Fi card with a 4G Mini PCIe modem, the two gold sockets will house the mobile coverage antennas (Main and Aux), which work together with the SIM card slot integrated into the board.
-
Internal exclusivity: The device has only one internal Mini PCIe (half-size) slot. This means you must choose between internal Wi-Fi/Bluetooth or internal 4G LTE connectivity. If you require both simultaneously, the most practical solution is to mount the 4G modem internally and use an external USB Wi-Fi adapter.
Advantages of dual Ethernet ports (2× LAN)
The presence of two independent physical Gigabit interfaces offers advanced possibilities for local area networks and servers:
-
Firewall/Router Configuration: You can use one port as an internet entry port ( WAN ) and the other to distribute local wired network ( LAN ), perfect for environments with distributions such as OPNsense, pfSense or Linux-based firewalls.
-
Control network isolation (physical VLAN/DMZ): Allows one card to be connected to the regular office network and the second to be strictly connected to a subnetwork of machinery, IP cameras or industrial terminals without an internet connection.
-
High availability or aggregation (Bonding): In Windows Server or Linux systems you can group both links to add transmission capacity or have redundancy if one of the network cables suffers a cut.
Expansion and internal components
Accessing the interior requires removing four screws in the lower metal base:
-
RAM: Versions with 12th and 13th generation Intel processors feature a single DDR5 SODIMM socket, supporting individual modules up to 32 GB. If you choose the barebone model, you can purchase a DDR5 SODIMM RAM module on AliExpress to complete your system.
-
Primary SSD: The slot supports M.2 2280 form factor drives, both NVMe and SATA. If you need more fast storage capacity, you can find an M.2 2280 NVMe SSD on AliExpress at a good price.
-
Secondary storage: The internal bay allows you to screw in a 2.5-inch solid-state drive or mechanical hard drive using the included SATA flex cable. For large-scale backups, it's recommended to add a 2.5-inch SATA SSD from AliExpress.
