Choosing a PC for an industrial PC, SCADA, or edge-control station usually comes down to two directions: a conventional small-form-factor desktop with legacy ports and an optical drive, or a compact mini PC that can sit near the controller. In this head-to-head, the HP Business Class Desktop at USD 184.99 and the KAMRUI GK3Plus Mini PC at USD 159.00 both run Windows 11 Pro. The HP is a very good refurbished unit; the KAMRUI is new. Which one fits your panel, bench, or control room?
Quick Verdict
If your edge-control setup depends on a serial port, a DVD drive, and a familiar SFF chassis, the HP Business Class Desktop is the pick. If you want a smaller, brand-new machine with 4K UHD over dual HDMI and a lower listed price, the KAMRUI GK3Plus makes sense.
Where Each Wins
- HP Business Class Desktop: Lists a DVD drive, serial port, VGA, DisplayPort, and Gigabit Ethernet, plus 16GB RAM and an Intel quad-core 3GHz CPU in an SFF chassis.
- KAMRUI GK3Plus Mini PC: The new mini PC lists 12GB LPDDR4, 256GB SSD, dual HDMI 2.0, VGA, USB 3.2 Gen1, and Wi-Fi 5 in a compact silver chassis with 4K UHD output.

Product Notes
HP Business Class Windows 11 Pro Intel Quad Core 3GHz SSD DVD WiFi 16GB Desktop
The HP is the more traditional option. Its very good refurbished SFF desktop comes with 16GB RAM, a DVD drive, and a serial port, which can be handy for connecting older industrial peripherals. It also lists VGA, DisplayPort, USB 2.0/3.0, audio jacks, and Gigabit Ethernet, so it covers most wired setups. The main limitation is the condition: it is refurbished rather than new. If you need the optical drive and legacy I/O, this is the stronger reason to choose it.
KAMRUI GK3Plus Mini PC, Intel N5030 12GB LPDDR4 256GB SSD 4K UHD Windows 11 Pro
The KAMRUI is the compact, new alternative. It lists dual HDMI 2.0, VGA, USB 3.2 Gen1, and Wi-Fi 5, and its 4K UHD support makes it easy to pair with two displays for an edge-control dashboard. The 12GB LPDDR4 is soldered, so the memory is fixed, and storage is 256GB SSD. The trade-off is the soldered RAM: what you buy is what you get. If your setup leans on a serial port, the HP's connectivity list includes one.
Final Choice by Use Case
- Choose the HP Business Class Desktop if you need the SFF chassis with a DVD drive and a serial port, and if a very good refurbished unit fits your budget.
- Choose the KAMRUI GK3Plus Mini PC if you want a new, compact Windows 11 Pro machine and can work with its 12GB soldered LPDDR4 and 256GB SSD.
For a SCADA or edge-control panel where space is tight and 4K dashboards are the priority, the KAMRUI is the compact pick. For a bench or rack with legacy serial gear and optical media, the HP is the conventional choice.
