Overview
- fit compute close to the workload (edge rooms, kiosks, lab benches).
- small volume needs correct fan selection and clear airflow paths.
- pick PCIe (riser/low-profile) and I/O up front.
- tool-less panels, fast access to fan/filters, simple cable routing.

Recommended configuration
- ITX case with balanced bays and airflow for small storage builds.
- Consider NAS case families for higher bay density.
- Pre-assembly services for repeat builds.
Selection Checklist
| Cooling | Fan size/quantity, CPU cooler clearance, hot zones (VRM/NIC/drive), noise targets. |
|---|---|
| Airflow | Intake/exhaust path, dust filter access, cable obstruction control, kiosk/cabinet clearance. |
| PCIe | LP/FH clearance, riser support, slot placement, card length/height limits, thermal impact. |
| Power | PSU form factor (Flex/ATX/SFX if applicable), wattage headroom, connector planning. |
| Drive bays | 3.5″/2.5″ count, SSD cache options, vibration considerations for HDDs. |
| Motherboard | Mini-ITX support, I/O alignment, internal headers, cooler height constraints. |
| Depth | Overall depth, rear cable bend radius, mounting clearance in cabinets/kiosks. |
| Rails | Usually N/A for ITX; consider wall/kiosk brackets, VESA mounts, or short-depth rack trays if needed. |
| Maintenance | Tool-less panels, fan/filter access, quick swap workflow, clear labeling for service. |
FAQ
What is an ITX case?
An ITX case is a compact chassis designed to fit Mini-ITX motherboards. It’s commonly used for space-constrained edge, embedded, and compact workstation/storage builds.
Can an ITX case support PCIe expansion cards?
Yes—depending on the chassis design. Many ITX cases support low-profile cards or use risers to accommodate specific PCIe layouts. Always verify card height/length and airflow impact.
What PSU types are common for ITX cases?
Common options include Flex PSU and compact ATX/SFX-style PSUs (depending on chassis). Choose based on required wattage, connectors, and available internal space.
How do I plan cooling in a compact ITX enclosure?
Confirm CPU cooler height clearance, fan size/placement, and a clean intake/exhaust path. For dusty environments, prioritize filter access and easy cleaning.
How many drives can an ITX case hold?
It varies by model. Many ITX cases support a small number of 2.5" SSDs and/or 3.5" HDDs. For higher bay density, consider NAS chassis categories.
When should I choose ITX vs rackmount or wallmount cases?
Choose ITX for compact, local deployments and kiosks. Choose rackmount for standardized rack deployment and higher expansion. Choose wallmount when you need wall installation and easy front access.
What details should I send for an ITX case recommendation?
Share motherboard, CPU cooler height, PCIe cards (LP/riser needs), drive count, PSU preference, depth/mounting constraints, and ambient conditions.
Do you offer OEM/ODM customization for ITX cases?
Yes. Customization can include I/O cutouts, bracket/mounting changes, drive bay layout adjustments, branding, and assembly services.
