AI Verdict
This 8-liter Micro-ATX case with an included 265W power supply is a cheap, space-saving shell for basic office builds or low-power home servers, but don't expect silent operation.
This case is a fantastic value if you are building a low-power office machine or a headless NAS using integrated graphics. The 265W power limit, 45mm cooler clearance, and lack of PCIe power cables make it completely unviable for modern gaming builds.
If you plan to add a dedicated low-profile GPU later, look for an SFF case that supports standard SFX power supplies so you can upgrade past 265W.

Pros
- Fits standard Micro-ATX motherboards inside an ultra-compact 8-liter footprint
- Includes a pre-installed 265W Flex ATX power supply with 24-pin and 8-pin CPU connectors
- Tool-free drive cage holds a slim optical drive, a 3.5-inch drive, and a 2.5-inch drive simultaneously
- Massive side panel cutout directly over the CPU socket provides excellent intake airflow
- Solid metal side panels block dust better than fully meshed SFF cases
Cons
- The included 265W power supply fan is notorious for developing a grinding noise after 10 to 16 months
- Front panel USB-C is advertised but requires an optional, hard-to-find accessory cable
- CPU cooler clearance is strictly limited to 45mm, forcing you to remove shrouds on stock AMD Wraith Stealth coolers
- Zero documentation included in the box for the front panel header pin layout
Dimension Scores
The 265W PSU is plenty for 65W CPUs and basic office tasks, but lacks any PCIe power for dedicated GPUs.
The tiny Flex ATX power supply fan is prone to whining and frequently develops a grinding noise after a year.
The metal chassis is sturdy and the tool-free drive cage works well, but the lack of an included USB-C cable feels cheap.
There is virtually no space behind the motherboard tray, forcing you to stuff excess PSU cables into the empty optical drive bay.
Best For
- Basic home office PCs using 65W CPUs like the Intel Core i3/i5 or AMD Ryzen 5600G
- DIY NAS builds utilizing the 3.5-inch and 2.5-inch drive bays
- Budget-conscious builders who want a case and power supply combo under $100
Not Recommended For
- Gaming PCs requiring a dedicated graphics card, as it only supports low-profile GPUs and lacks PCIe power cables
- Silent PC enthusiasts, due to the whiny 80mm case fan and Flex ATX power supply fan
Watch Out For
- The front USB-C port is just a blank cutout — you have to hunt down a proprietary In Win cable to actually use it.
- The included power supply fan has a high failure rate, often developing a loud grinding noise within the first year of daily use.
- CPU cooler clearance is extremely tight at 45mm; standard AMD Wraith Stealth coolers will rub against the side panel unless you remove the plastic shroud.
- The front panel connectors use a non-standard pin layout and the case ships with zero instruction manual to help you wire it.

What Buyers Say
The included 265W power supply drives a love-hate relationship among builders. Getting an 8-liter Micro-ATX case and a PSU for under $100 makes this a go-to for budget office PCs and DIY NAS setups. The thermal design gets high marks because the massive side panel cutout feeds fresh air directly to the CPU cooler. The major downside is a reported 25% failure rate for the power supply fan, which starts grinding after 10 to 16 months of continuous use. The 'optional' front USB-C port also frustrates builders because it is just an empty hole out of the box.
“Great little case for an office build but the power supply fan started grinding like a blender after 10 months and there's no manual for the weird front panel pins.”
Common Praise
- Unbeatable value for getting both an 8L case and a 265W power supply
- Direct CPU intake vent keeps 65W processors surprisingly cool
- Tool-free drive cage makes installing 2.5-inch and 3.5-inch drives incredibly fast
- Solid metal panels keep dust out better than fully ventilated mesh cases
Common Complaints
- Power supply fan develops a loud grinding noise after a year
- Front USB-C port is just a blank cutout requiring a separate purchase
- Zero documentation for the confusing front panel header pins
- 45mm CPU cooler clearance forces modifications to stock AMD coolers
Ownership Tips
- Flipping the case upside down in vertical mode actually improves thermals by letting the top exhaust heat naturally.
- If you don't install a slim optical drive, that empty bay is the only place to hide the excess power supply cables.
- Replacing the grinding PSU fan is possible but requires opening the power supply and voiding the warranty.
Frequently Asked Questions
Does this case come with a power supply?
Yes, it includes a 265W Flex ATX power supply pre-installed. It has standard 24-pin motherboard and 8-pin CPU connectors.
Will an AMD Wraith Stealth stock cooler fit?
Barely. You have to unscrew and remove the plastic Ryzen logo ring from the cooler, and even then it will slightly press against the side panel grill.
Can I fit a dedicated graphics card in this?
Only low-profile, half-height graphics cards that don't require external PCIe power cables, like a GTX 1650 LP or RX 6400.
How do I get the front USB-C port to work?
The case only has a cutout for USB-C. You have to buy an optional In Win accessory cable separately, which is currently very difficult to find in stock.
Is the power supply loud?
Out of the box it's audible but acceptable, but many buyers report the tiny PSU fan starts making a loud grinding noise after about a year of use.
Does it support full-size ATX motherboards?
No, it only fits Micro-ATX (mATX) and Mini-ITX motherboards.
Buying Guide
When buying an ultra-compact 8-liter case like this, you are trading expansion for desk space. You must verify your CPU cooler is under 45mm tall, or the side panel simply won't close. Because this uses a specialized Flex ATX power supply, replacing it if it dies costs more than a standard ATX unit. You also cannot use standard graphics cards here — you are strictly limited to half-height, low-profile cards that draw all their power directly from the motherboard.
8L Volume
Think of this as the physical footprint. At 8 liters, it's about the size of a thick textbook, taking up a fraction of the space of a standard 40-liter mid-tower PC.
Flex ATX Power Supply
This is a long, skinny power supply designed for servers and tiny cases. They use smaller 40mm fans to cool themselves, which have to spin much faster and louder than the large fans in normal desktop power supplies.
Micro-ATX Compatibility
This is the size of the motherboard it accepts. Micro-ATX boards are usually the cheapest on the market, making this case great for budget builds compared to cases that only accept expensive Mini-ITX boards.
Alternatives
If you want to build a compact gaming PC with a dedicated graphics card, look for an SFF case around 11 to 15 liters that supports SFX power supplies and full-height, dual-slot GPUs.
