Choosing a PC for a SCADA workstation or an edge-control role usually means balancing compactness, legacy port support, and day-to-day responsiveness. The four Windows 11 Pro desktops below cover that balance, with a listed price spread of $62.47 from the least to most expensive unit. Two are new KAMRUI mini PCs, one is a refurbished HP small form factor desktop, and one is a refurbished Dell small form factor desktop aimed at higher RAM and storage capacity.
Quick take
If you want a new, tiny Windows 11 Pro machine for 4K dashboards and light monitoring, the KAMRUI GK3Plus builds are the entry-priced options. If you need legacy serial connectivity, a DVD drive, and a more conventional desktop footprint, the HP Business Class sits in the middle of the pack. If your priority is RAM and storage headroom for larger SCADA databases, the Dell is the upper-priced pick with the most capacity-oriented specification.

Product notes
KAMRUI GK3Plus Mini PC, Intel N5030 12GB LPDDR4 256GB SSD 4K UHD Windows 11 Pro
The silver KAMRUI GK3Plus is listed at $159.00, making it one of two new mini PCs at the entry point of this group. Its Intel N5030 quad-core processor, 12GB LPDDR4 RAM, and 256GB SSD are tuned for everyday office work, web-based SCADA screens, and light local logging. The port selection includes dual HDMI 2.0, VGA, USB 3.2, and Gigabit Ethernet, so you can attach two 4K displays without a separate dock. The main constraint is storage: 256GB is enough for Windows 11 Pro and a few applications, but a machine doing continuous edge logging will want network storage or an external drive.
KAMRUI 4K Mini PC GK3Plus, Intel N5030 12GB LPDDR4 256GB M.2 SSD Win11 Pro WiFi5
The black KAMRUI GK3Plus also lists at $159.00, giving you a color alternative at the same price. It keeps the N5030 processor, 12GB RAM, and 256GB M.2 SSD, with 4K UHD output through dual HDMI, plus USB 3.2, Gigabit Ethernet, WiFi 5, and Bluetooth 4.2. The black unit's port set is built around HDMI and USB, while the silver GK3Plus adds a VGA port to its connectivity list. For a dashboard station that feeds two modern 4K monitors, this is a clean, low-desk-space option. The limitation is the same 256GB storage as the silver unit, which means large local data logs will need to be stored elsewhere.
HP Business Class Windows 11 Pro Intel Quad Core 3GHz SSD DVD WiFi 16GB Desktop
The HP Business Class desktop is listed at $184.99 and brings a more traditional small form factor to the group. It is a Very Good refurbished unit with a 3GHz Intel quad-core processor, 16GB RAM, SSD storage, a DVD drive, and a USB Wi-Fi 6/Bluetooth adapter. For SCADA and edge-control work, the standout is the connectivity: serial port, VGA, DisplayPort, and Gigabit Ethernet cover the kind of older peripherals and industrial test gear that still rely on legacy ports. The package includes a keyboard, mouse, and power cables. The tradeoff is condition: this is a refurbished business PC, so you are buying a professionally inspected used unit rather than a new-in-box system.
Dell Windows 11 Pro Desktop Computer PC Up To i7 8th Gen. 32GB RAM 4TB SSD/HDD
The Dell desktop is the highest listed price at $221.47, but its specification points toward larger workloads. The title advertises up to an 8th Gen Intel Core i7, 32GB RAM, and a 4TB SSD/HDD combination, making it the only unit in this group aimed at serious data storage. It is an Excellent refurbished small form factor desktop with HDMI, DisplayPort, USB 3.0, RJ-45, an optical drive, and Wi-Fi. Because the title uses "up to" wording, the exact build sits within a range rather than being pinned to one processor, RAM, and storage combo. That flexibility is useful when you are shopping for a particular budget, but it also means the delivered build can vary within the advertised range.
Final call
For a compact new PC that handles 4K SCADA dashboards with minimal desk space, start with either KAMRUI GK3Plus. Choose the silver version if VGA is part of your monitor setup; choose the black version if you prefer the same core specs in an all-black finish. If your control room uses legacy serial equipment or you want the convenience of a DVD drive and a full desktop package, the HP Business Class is the middle solution. If storage and RAM headroom are the bigger concerns, the Dell is the upper-end option for heavier edge-data workloads.
