Picking a compact industrial PC for SCADA and edge control means balancing more than processor speed. You need a small chassis that fits a panel or cabinet, enough RAM and storage for local data, reliable connectivity, and an operating system your software stack already supports. The four desktops here price out across a useful range, so the real decision is about matching trade-offs to your plant floor, control room, or remote edge site.
Quick take: If your environment calls for a dedicated industrial box, the Dell Embedded Box PC 5000 is the one to watch. If local memory and storage are the bottleneck, the Dell Windows 11 Mini Desktop has the largest capacity. If graphics output matters more than raw storage, the Lenovo ThinkStation P320 Tiny is the best fit. The Lenovo ThinkCentre M715q Tiny rounds out the group with a modern OS and a balanced feature set.

Product notes
Lenovo ThinkCentre M715q Tiny
The M715q Tiny is the all-rounder of this group. It runs Windows 11 Professional, a plus if your SCADA or edge software has moved off Windows 10. The AMD Ryzen 5 Pro processor is paired with 16GB of DDR4 RAM and a 1TB SSD, giving you a comfortable memory footprint and enough local storage for logs and trend data. It can drive up to dual 24-inch displays, making it easy to run an HMI and a data view side by side. The Micro Form Factor chassis is ultra-slim, and connectivity includes USB 3.1, DisplayPort, RJ-45, and audio ports. The main limitation is the integrated Radeon Vega graphics: fine for typical HMI screens, but not a replacement for a dedicated GPU if your edge workload includes heavy 3D visualization. At $199.99, it's a strong balance of modern OS, capacity, and price.
Dell Embedded Box PC 5000
This Dell is the one that looks like it belongs in a control cabinet. Its fanless design is a concrete advantage in dusty or hot environments where a cooling fan can pull in contaminants or fail over time. Inside, the Core i7-6820EQ runs at 2.8GHz and comes with 8GB RAM and a 512GB SSD. The maximum RAM capacity is 32GB, so there is room to grow if your edge workload expands. It also offers a wide port selection: VGA, HDMI, DisplayPort, and USB 3.x. Windows 10 Pro is installed. The trade-off is that the stock 8GB RAM is modest for running multiple SCADA applications at once, and the unit is listed as used. At $200.00, its value comes from its industrial-oriented build rather than raw specs.
Dell Windows 11 Mini Desktop
The Dell Windows 11 Mini Desktop is the capacity leader at $282.00. It pairs 32GB of RAM with a 1TB SSD, which makes it the best choice in this lineup if you run data-heavy SCADA clients, edge analytics, or multiple virtual machines. It comes with Windows 11, built-in Wi-Fi, and HDMI & VGA adapters in the package, along with USB 3.0, DisplayPort, Ethernet, and audio jacks. The ultra-slim chassis fits the same compact spaces as the others. The limitation is price: it costs noticeably more than the other three, and it is listed as used. If the workload really needs 32GB and 1TB, the extra money is justified. If not, you may be paying for capacity you will not use. This one makes sense when local memory and storage are the bottleneck.
Lenovo ThinkStation P320 Tiny
The P320 Tiny is the value-focused pick at $159.99, and it is the only unit here with dedicated graphics. The NVIDIA Quadro P600 makes it a sensible choice for multi-display HMI setups, digital signage, or CAD-type work at the edge. It also includes built-in Wi-Fi and Bluetooth, plus a small USFF case with DisplayPort, Mini DisplayPort, RJ-45, and USB 3.0. Windows 10 Pro is installed. The catch is storage: a 128GB M.2 SSD is enough for the operating system and a handful of SCADA clients, but it will fill up quickly if you store years of historical data locally. The condition is Very Good - Refurbished, and it is the least expensive entry point in this comparison. If your task is graphics acceleration rather than huge data archives, this is the easiest way to get workstation-class graphics in a tiny box.
Final recommendation by use case
Choose the Dell Embedded Box PC 5000 when your priority is an industrial-oriented chassis. Choose the Dell Windows 11 Mini Desktop when you need the most local capacity for data-heavy work. Choose the Lenovo ThinkCentre M715q Tiny for a balanced SCADA/edge workstation that runs a modern OS. Choose the Lenovo ThinkStation P320 Tiny when you want the GPU-driven edge box and a lower entry price. Match the machine to the environment and workload, and any of these can handle the job.
