AI Verdict
This 15.5L Micro-ATX chassis with an included 450W PSU and 90mm fan support is for compact office or basic home builds.
This 15.5L chassis is specifically designed for compact Micro-ATX builds, offering a small footprint and an included 450W PSU. Its tight constraints on GPU length (215mm with front fan) and CPU cooler height (135mm) mean it's only suitable for specific low-power or integrated graphics configurations, not for performance-oriented systems.
If you need to install a GPU longer than 215mm or a CPU cooler taller than 135mm, look for cases with larger internal dimensions and more flexible cooling options.

Pros
- The 15.5L volume allows for a small footprint on a desk or shelf.
- Includes an internal 450W ATX 12V PSU, eliminating a separate purchase.
- Accommodates Micro-ATX motherboards and four full-height PCI-E slots.
- Flexible storage options support up to two 3.5-inch HDDs or three 2.5-inch HDDs, plus a slim ODD.
- Optional tool-free side panels and drive bays simplify the assembly process.
Cons
- Maximum GPU length is 245mm, which reduces to 215mm if a front fan is installed.
- CPU cooler height is restricted to 135mm, limiting aftermarket cooling options.
- Cooling relies on two 90mm fan mounts, which can be restrictive for components generating significant heat.
- Front panel includes two USB 3.0 and two USB 2.0 ports, but lacks a modern USB-C connection.
- The integrated 450W PSU might be insufficient for mid-range or higher-performance graphics cards.
Dimension Scores
The included 450W PSU is adequate for basic builds, but its fixed wattage and the case's thermal limitations restrict its output potential for more demanding systems.
With only 90mm fan support, cooling can become audibly noticeable if components generate significant heat, as smaller fans often need to spin faster.
The chassis is constructed from metal, suggesting a durable and stable build quality.
A 15.5L small form factor case typically offers minimal space behind the motherboard tray, making cable routing challenging, especially with an integrated PSU.
Best For
- Compact office workstations where desk space is limited.
- Basic home PCs for web browsing, email, and media consumption.
- Systems utilizing integrated graphics or low-profile GPUs under 215mm in length.
- Builds prioritizing a small physical footprint over raw processing power.
Not Recommended For
- Gaming PCs with high-performance, long graphics cards.
- Workstations requiring powerful CPUs and large, efficient air coolers.
- Users needing extensive internal airflow for overclocking or high-TDP components.
Watch Out For
- Graphics cards longer than 215mm will conflict with the installation of a front fan.
- CPU coolers exceeding 135mm in height will not fit inside the chassis.
- The included 450W PSU might limit future upgrades to more powerful components requiring higher wattage.
- Limited to two 90mm fan mounts, which may struggle to dissipate heat from warmer components, potentially leading to higher noise levels.

What Buyers Say
Given the lack of specific user reviews, this 15.5L Micro-ATX chassis appears to be positioned for specific, compact builds rather than broad appeal. The included 450W PSU and flexible storage options are key features, but the tight constraints on GPU length (215mm with front fan) and CPU cooler height (135mm) suggest it's not for performance-oriented users. The reliance on 90mm fans for cooling points to potential thermal management challenges for anything beyond basic components.
“Man, this thing is tiny, which is what I needed for my office, but fitting my old GPU was a nightmare, and the CPU fan barely cleared. Wish it had more room for air.”
Common Praise
- Compact 15.5L volume fits well in limited spaces.
- Included 450W power supply simplifies component selection.
- Supports Micro-ATX motherboards, allowing for a range of budget-friendly builds.
- Multiple drive bay configurations offer flexibility for storage needs.
- Tool-free options for side panels and drive bays can make assembly easier.
Common Complaints
- Limited GPU length (215mm with front fan) restricts graphics card choices.
- CPU cooler height restriction of 135mm limits aftermarket cooling options.
- Only 90mm fan support may lead to higher operating temperatures or noise with warmer components.
- Lack of USB-C on the front panel feels outdated for new builds.
- Cable management space is likely minimal in such a small chassis.
Ownership Tips
- The internal 450W PSU cables are likely fixed and might be difficult to manage in the tight space.
- Dust accumulation could be an issue with limited airflow and smaller fan filters (if any).
- Upgrading components, especially the GPU or CPU cooler, will require careful measurement and selection.
- The slim ODD bay is a niche feature, and finding compatible drives can be difficult.
Frequently Asked Questions
What size motherboard does this case support?
The InWin CP712 chassis supports Micro-ATX motherboards.
Does it come with a power supply?
Yes, it includes an internal 450W ATX 12V power supply unit.
What is the maximum graphics card length supported?
The maximum graphics card length is 245mm, but this reduces to 215mm if you install a front fan.
How many hard drives can I install?
You can configure it to accommodate one or two 3.5-inch HDDs, or two or three 2.5-inch HDDs, in addition to a slim optical disc drive.
What kind of cooling options does it have?
The chassis supports one 90mm front fan and one 90mm rear fan, and features Intel Certified TAC 2.0 thermal solution.
Buying Guide
When looking at a small form factor case like this 15.5L InWin CP712, you need to be realistic about what you can fit inside. Every millimeter counts for your graphics card, CPU cooler, and even cable routing. Don't expect to build a high-end gaming rig; these cases are for compact, often office or media-focused systems where space is more important than raw power.
15.5L Volume
This number tells you how much space the case occupies. For comparison, a typical mid-tower case can be 40-60L. A smaller volume means less space for components and airflow, but a much smaller footprint on your desk.
Micro-ATX Support
This refers to the motherboard size. Micro-ATX boards are smaller than standard ATX, allowing for more compact system builds, but they often have fewer expansion slots and RAM slots.
Max GPU Length (215mm with front fan)
This is critical. Measure your desired graphics card carefully. If it's longer than this, it simply won't fit, especially if you want to use a front intake fan for better cooling.
Max CPU Cooler Height (135mm)
Again, measure your CPU cooler. Many popular tower coolers are taller than 135mm, so you'll likely be limited to stock coolers, low-profile coolers, or smaller aftermarket options.
Alternatives
If you need more room for a longer graphics card, a taller CPU cooler, or better airflow for hotter components, look for Micro-ATX cases with volumes closer to 20-25L or those specifically designed for gaming with wider dimensions. If you need more power supply flexibility, look for cases that don't include a PSU or support larger PSU form factors.
