Choosing between these four industrial PC listings for SCADA and edge control comes down to how much legacy serial hardware you need, how much RAM and storage your control software will consume, and how much footprint you can allocate in the control cabinet or desk.
Quick take
The four listings cover the practical spread: a Qotom mini PC built for POS/IPC serial work, an HP business desktop with a serial port and DVD drive, a Chuwi mini PC with Windows 11 and an Intel N100, and a Dell micro desktop with 32GB RAM and a 1TB SSD. None is a universal winner; each maps to a different edge-control role.

Product notes
Qotom Q310p 3205u 4GB 32GB SSD Mini PC COM Serial Port IPC POS Computer RS-232
The Qotom Q310p is the listing that looks most at home in a SCADA or edge-control rack: it is offered as a very-good refurbished mini PC with a 4GB RAM/32GB SSD configuration, six COM ports, two LAN ports, and multiple USB 3.0 ports. The description notes it is designed for industrial use, casual computing, engineering coding, and office work, and it supports Windows, pfSense, and Linux. The main limitation is that no OS is included, so you will need to supply your own operating system. If your edge device talks over RS-232 or RS-485, the Qotom's serial-port layout is the strongest reason to start here.
CHUWI HEROBOX MINI PC Windows 11 Mini Desktop Computer Intel N100 3.4Ghz 8G 256G
The CHUWI HEROBOX is a new Windows 11 mini desktop with an Intel N100 processor running up to 3.4GHz, 8GB RAM, and a 256GB SSD. It gives you a practical set of display options-HDMI, VGA, and USB-C-plus USB 3.0, a built-in Wi-Fi adapter, SD card slot, and VESA mount. The listing also describes the storage as expandable through an M.2 SATA slot and a 2.5-inch SATA bay. It is a good choice if you want a brand-new, compact edge-control PC with two-monitor capability, but the 8GB memory and the absence of a serial port in the port list mean you should plan for a USB-to-serial adapter when connecting older SCADA equipment.
HP Business Class Windows 11 Pro Intel Quad Core 3GHz SSD DVD WiFi 16GB Desktop
The HP Business Class desktop is a very-good refurbished small-form-factor PC that bundles a 16GB RAM system with an SSD, DVD drive, Wi-Fi, Bluetooth, and a serial port-handy if your edge-control desk still needs optical media or legacy connections. Its Intel Quad Core 3GHz processor positions it as a solid everyday office and control-room machine. The trade-off is form factor: this is an SFF desktop rather than a stick-style or mini edge node, so it takes up more room. The refurbished condition also means you should expect normal signs of prior use.
Dell Windows 11 Mini Desktop up to PC i7 8th, 32GB RAM, 1TB SSD, Built-In WiFi
The Dell Windows 11 Mini Desktop is the highest-specified listing here: 32GB RAM, 1TB SSD, built-in Wi-Fi, and a micro-form-factor chassis. The package includes HDMI and VGA adapters, and the listing describes it as fully tested, clean, and showing at most minor cosmetic wear. This is the one to choose when edge-control software needs lots of memory and local storage for logs, models, or databases. The trade-off is the used condition and the highest listed price of the group, so it is better suited to applications that will actually use that capacity.
Final recommendation by use case
- Start with the Qotom Q310p if your SCADA or edge device relies on RS-232/RS-485 and you want the most serial connectivity at the lowest listed price.
- Choose the CHUWI HEROBOX if you prefer a new mini PC with Windows 11, dual display output, and room to expand storage.
- Take the HP Business Class SFF when the deployment is a control-room desktop where a DVD drive, Bluetooth, and serial port are part of the daily workflow.
- Pick the Dell Windows 11 Mini Desktop when your edge-control workload needs the 32GB RAM and 1TB SSD combination for local processing and log storage.
