When you're building or updating a control panel, the HMI is the operator's main window into the PLC. Deciding which HMI component to buy gets tricky because you might need a full industrial computer, a display for parts or repair, or just a mounting bracket for a screen you already have. These four PLC/HMI options cover exactly those scenarios, with listed prices from $200 to $795. The range includes two used industrial PC/HMI units, one large touchscreen monitor sold strictly for parts and repair, and one new HMI monitor mount.
Quick take
If you need a complete Windows HMI environment at the lowest listed price, the Parker IXA-000-3N3-53 IX InteractX PowerStation is the most direct candidate. If you need a compact fanless box PC for legacy Atom-based HMI work, the Avalue EES-AT270 fits that role. If you need components from a 21.5-inch industrial touchscreen, the StrongArm monitor is explicitly sold for parts/repair. If you already have a display and need a vibration-resistant mount, the Industrial Display Bracket HMI Monitor Mount is the new accessory in the group.

Product notes
StrongArm 404-215T0A 21.5\" Industrial Touchscreen HMI Monitor Parts Repair
The StrongArm 404-215T0A 21.5\" Industrial Touchscreen HMI Monitor is listed for parts or repair, not as a working unit. It is a 21.5-inch widescreen display with 1920 × 1080 resolution, resistive touch, DVI and VGA video inputs, serial and USB touchscreen interfaces, and 100-240 VAC power input. The description shows cosmetic wear and notes that the monitor may need repair or replacement parts. Choose it when you need that exact panel or touch screen for a maintenance job. If you expect to power it up and use it immediately, this listing is not the right fit because it is explicitly being sold as-is for parts or repair.
Avalue EES-AT270 BOX PC Industrial HMI System Atom N270 Touchscreen Monitor
The Avalue EES-AT270 is a used industrial box PC built around an Intel Atom N270 processor and an Intel GSE + ICH7M chipset. It includes one 200-pin SO-DIMM slot for DDR2 667 MHz memory up to 2GB, a 2.5-inch SATA drive bay, and support for Windows XP, 7, CE 6.0, and Linux. The I/O list includes VGA, one COM port, one RJ45 LAN port, two USB 2.0 ports, and audio line-in/line-out. It also lists a fanless 12 VDC design and dimensions of 200 x 120 x 68.5 mm. The limitation is its used, legacy nature: this is an older Atom platform, so you should think about driver and OS compatibility before building a current project around it.
Parker IXA-000-3N3-53 IX InteractX PowerStation Industrial PC HMI
The Parker IXA-000-3N3-53 IX InteractX PowerStation is a used industrial PC/HMI that comes with Parker's InteractX software environment, according to the description. It lists programmable features such as bar graph support, data entry, Ethernet support, real-time graph support, USB, and VGA. The description says InteractX works out of the box without special IT skills and offers styles, templates, and a toolbin for sharing screens. This is the lower-priced listing in the group, but the unit has one screw missing from the SSD cover, visible in the photos. If you want a Windows HMI system with a modest entry point and can accept minor cosmetic wear, this is the strongest all-around candidate.
Industrial Display Bracket HMI Monitor Mount Vibration Resistant
The Industrial Display Bracket HMI Monitor Mount is the one new product in this set and the only one made for mounting a display rather than running HMI software. The listing type is desk mount, and the description highlights a vibration-resistant structure, anti-collision buffer design, modular detachable construction, strong load-bearing support, and a dust-resistant rubber ring. It is useful when you have an industrial monitor or HMI screen that needs to be attached to a control desk or equipment frame and you want some shock and dust protection. It does not include a monitor, touchscreen, or computer, so it is a supporting component rather than a standalone HMI system.
Final recommendation
If a complete, working HMI system is the priority and budget matters, start with the Parker IXA-000-3N3-53 IX InteractX PowerStation: it's the lowest-priced listing in the group and includes InteractX software. For a compact fanless box PC with legacy connectivity, the Avalue EES-AT270 is the one to consider. If you need parts from a 21.5-inch industrial touchscreen, the StrongArm 404-215T0A is sold explicitly for parts and repair. If all you're missing is a stable mount for an existing display, the Industrial Display Bracket HMI Monitor Mount is the new accessory to pair with whatever HMI screen you already have.
