Why Mini ITX Cases Are Exploding in Popularity
The mini ITX form factor has existed for over 15 years, but only now is the demand really accelerating for ultra compact cases and components that conform to its 6.7 x 6.7 inch dimensions. According to Jon Peddie Research, mini ITX motherboard shipments expanded over 50% annually the last 3 years.
I see 5 key factors fueling their surging adoption:
- Space Savings – With remote work booming, mini ITX cases cut home office clutter. mITX builds claim 25-50% less volume than micro ATX.
- Portability – Compact, lightweight mini ITX builds easily transport to LANs, tradeshows and anywhere Needed without compromising performance.
- Customization – Mini ITX cases compact specialized builds for gaming, streaming, content creation etc. into a personalized, unique footprint. Gamers particularly value transporting top-tier power to tournaments.

- Maturing Components – GPUs, CPUs and PSUs continually improve performance per mm enabling more speed within mITX confines. Nvidia‘s 40 series graphics substantially boost efficiency. Intel and AMD‘s latest processors extend high core counts and features to 65W options perfect for compact chassis. SFX power supplies now deliver over 850W.
- Innovative Designs – Case manufacturers leverage clever layouts like dual orientable chambers and vertical stacking to maximize mITX potential. Features like toolless drive bays enhance their builder-friendliness.
As components scale down and ambitions for unique builds scale up, mini ITX offers the ultimate blend of personalization, portability and performance at reasonable pricing. But effectively utilizing the stricter space does require some guidance…
What Exactly Are Mini ITX Cases?
True mini ITX cases adhere precisely to the 6.7 x 6.7 inch mini ITX motherboard specification for maximum compatibility. However, creatively designed models tailor interior layouts to still allow fitting full-length, full-height standard components like graphics cards.
They optimize airflow with strategically placed vents and mounting options for multiple fans or radiators. Noise dampening material helps keep decibels down despite any space constraints. Versatile, adjustable panels permit modifying components down the road within set limitations.
Essentially, mini ITX cases deliver everything towers do in a fraction of the volume. However, keen consideration around dimension-compatible parts remains vital to prevent frustration!
Average Mini ITX Case Properties:
- Volume – 8-20 L
- Dimensions – Any 2 under 15 inches
- GPU Clearance – 13 inches
- CPU Cooler Height – 6 inches
- Motherboard – Mini ITX (6.7 x 6.7 inches)

With mini ITX foundations set, let’s explore how to pick the ideal chassis.
Choosing Your Mini ITX Case – Key Decision Factors
While all mini ITX cases excel at space savings, their exact dimensions and layouts vary greatly in optimizing performance. As you evaluate options, consider these aspects:
Dimensional Clearances
Measure and verify adequate spacing for each component against the case’s listed allowances. Leave a couple extra mm of margin when possible to prevent choking airflow.
Common Mini ITX Case Clearances:
| Component | Typical Allowance |
|---|---|
| GPU Length | 130-330mm |
| CPU Cooler Height | 130mm |
| PSU | SFX, SFX-L, ATX |
| 3.5" Drive Bays | 0-1 |
| 2.5” Drive Bays | 1-4 |
Match all hardware to case clearances or risk chokepoints
Cooling Capacity
Their confined nature makes sufficient airflow critical in mini ITX builds. Evaluate fan mount numbers, locations and radiator support against your planned hardware.
Target 1 exhaust fan per major heat source at minimum. Large tower coolers often prove difficult to fit, making all-in-one liquid CPU solutions ideal.
Expansion Potential
Will you upgrade components down the road? Seek models with replaceable bracketry or modularity supporting future GPU/storage swaps or supplemental cooling.
Power Supply Options
What PSU size can the chassis accommodate? SFX units suffices for most builds but high core count CPUs or power hungry GPUs might necessitate SFX-L or ATX.
Appearance Style
Do you prefer understated minimalism or aggressive gamer looks? Glass for inside visibility or solid metal panels? This choice showcases your personality.
With those factors in mind, let’s examine 5 standout mini ITX cases to suit different needs and budgets.

How to Build a PC in a Mini ITX Case
Constructing a system around a mini ITX case introduces more intricacies versus standard ATX builds given their cramped confines. Carefully follow these planning and assembly tips to keep the process frustration-free:
Choose Dimension Compatible Components
Confirm each hardware piece – GPU, CPU cooler, drives etc. fit within the chassis allowances you’ve selected with a couple mm padding ideally.
Diagram the Layout
Sketch a component layout accounting for clearances before screwing anything in. Ensure all cables route cleanly without choking airflow.
Group Heat Sources
Position hot running parts like GPUs and PSUs aligned vertically when possible so heat rises directly into exhaust fans along the natural path of convection.
