AI Verdict
This 2U rackmount chassis supports M-ATX/ITX boards, dual 5.25" bays, 1x 2.5" SSD, 2x 3.5" HDDs, and low-profile, two-slot expansion cards.
This chassis is a situational fit for users building compact servers, especially those needing Micro ATX or ITX compatibility and flexible storage with 5.25" bays. Its support for redundant PSUs is a plus for uptime. However, the airflow obstruction from the 3.5" drive bracket and potential rack ear width issues mean it's not a universal solution.
If you need full-height expansion cards or guaranteed 19" rack ear width, look for 3U or 4U chassis options with explicit full-height card support and precise rack ear measurements.

Cons
- The 3.5" drive bracket can obstruct airflow from one of the two front 80mm fans.
- Rack ears are reported to be slightly over 19" in width, potentially causing fitment issues in some racks.
- Limited to low-profile, two-slot PCI/PCIe cards, restricting options for full-height expansion cards.
- User reports indicate unhelpful customer support regarding quality control issues.
Dimension Scores
Supports redundant power supplies and flexible storage, but the 3.5" drive bracket can hinder optimal cooling efficiency.
Users report quiet operation even under load, but this depends heavily on the 80mm fans chosen by the user.
Constructed from alloy steel, users describe it as well-built and sturdy with good material quality and fitment.
While not explicitly detailed, the compact 2U form factor and internal drive bay layout suggest average cable management capabilities for a server chassis of this size.
Best For
- Compact server builds requiring Micro ATX or ITX motherboards in a 2U rack space.
- Home lab enthusiasts needing flexible storage with 5.25" bays for optical drives or hot-swap cages.
- Users who need redundant power supply support in a space-constrained rack environment.
Not Recommended For
- Anyone needing full-height graphics cards or other full-height expansion cards.
- Users prioritizing maximum airflow for all drive bays without modifications.
- Those with strict 19" rack width requirements who cannot tolerate minor deviations.
Watch Out For
- The 3.5" drive bracket can block airflow from one of the two front 80mm fans, requiring users to consider alternative 5.25" bay solutions for better cooling.
- Rack ears might be slightly wider than 19 inches, leading to tight or difficult installation in some standard server racks.
- Customer support has been described as unhelpful and clueless when addressing product issues.

What Buyers Say
Many users found this 2U rackmount chassis to be a sturdy option for compact server builds, particularly appreciating its support for Micro ATX boards and redundant power supplies. However, a recurring issue is the 3.5" drive bracket's placement, which can block airflow from one of the front 80mm fans, prompting some to use 5.25" bay adapters for better cooling. There are also reports of the rack ears being slightly wider than 19 inches, making installation tricky for some.
“Man, this case is pretty solid for the price, but seriously, that 3.5 inch drive cage just chokes out one of the fans, had to move my drives to a 5.25 bay to get some air moving. And the rack ears were a pain to squeeze in, felt like I was gonna bend my rack.”
Common Praise
- Well-built and sturdy construction using alloy steel.
- Accommodates both single and redundant power supplies.
- Fits in a server cabinet without major issues for most users.
- Offers flexible storage with dual 5.25" bays, 1x 2.5" SSD, and 2x 3.5" HDD slots.
- Features dual USB 3.0 ports on the front for convenient connectivity.
Common Complaints
- The 3.5" drive bracket blocks airflow from one of the two front 80mm fans.
- Rack ears are slightly over 19" in width, causing fitment problems for some users.
- Customer support was unhelpful when dealing with product issues.
- Limited to low-profile expansion cards, restricting GPU or other card choices.
Ownership Tips
- You'll probably want to invest in a 5.25" hot-swap bay or adapter if you plan on using 3.5" drives and want optimal front fan airflow.
- Double-check your rack's exact internal width; a slight deviation from 19" on the chassis ears can make a big difference during installation.
- Be prepared to source your own 80mm fans, as the chassis only provides brackets for them.
- The low-profile card limitation is real; don't expect to put any full-size GPUs in here.
Frequently Asked Questions
What motherboard sizes does this chassis support?
It supports Micro ATX (M-ATX) and ITX motherboards, making it suitable for compact builds.
Can I install a redundant power supply?

How many hard drives and SSDs can I install?
You can install one 2.5" SSD and up to two 3.5" HDDs, in addition to devices in the dual 5.25" bays.
Are the front USB ports fast?
Yes, it features dual USB 3.0 ports with 5Gbps transfer speeds, which are also backward compatible with USB 2.0 and 1.1.

Buying Guide
When you're looking at a server chassis like this, you're essentially buying a metal box to house your server components. What matters most is if your motherboard fits, how many drives you can cram in, and if it'll actually slide into your server rack without a fight. Cooling is also a big deal; you don't want your expensive components overheating because the airflow is blocked.
2U rackmount form factor
This tells you the height of the chassis in a server rack. '2U' means it takes up two 'rack units' of space. The smaller the 'U' number, the less vertical space it occupies, which is crucial if you have a crowded rack.
Micro ATX (M-ATX) / ITX M/B support
This dictates the size of the motherboard you can use. M-ATX and ITX are smaller motherboard standards, meaning this chassis is designed for more compact server builds, not full-sized ATX boards.
Dual 5.25" Drive Bays
These are larger bays traditionally used for optical drives. In a server, they're often repurposed for hot-swap drive cages, fan controllers, or other accessories, giving you flexibility beyond just hard drives.
Alternatives
If this chassis doesn't fit your needs, look for 3U or 4U rackmount cases if you need full-height expansion card support or more internal space for cooling and cable management.
