AI Verdict
A 4U rackmount chassis with 24 12Gbps hot-swap 3.5" bays and E-ATX support, built for petabyte-scale storage servers.
This chassis is a strong contender if your primary need is housing 24 3.5" hot-swap drives and an E-ATX motherboard for a storage-heavy server. Its 12Gbps backplane and hot-swap fans are specific advantages for data-intensive, always-on environments. However, the limited CPU cooler and GPU clearance, along with the reliance on older USB 2.0 front ports, mean it's not a universal solution.
If you need more flexibility for CPU coolers or GPUs, look for chassis with greater internal clearance specifications (e.g., 165mm+ CPU cooler height, 300mm+ GPU length).

Pros
- Accommodates 24 3.5-inch 12Gbps hot-swap drives, allowing for petabyte-scale storage solutions.
- Supports large E-ATX motherboards (up to 12" x 13") for high CPU core counts and extensive PCIe expansion.
- Features three 120x38mm hot-swap PWM fans, ensuring cooling integrity during maintenance.
- Constructed from SGCC alloy steel, indicating a durable material.
- Allows for the installation of standard PC components, including some large GPUs with specific adapters.
Cons
- Front panel includes only two USB 2.0 ports, which is outdated for modern server builds.
- Max CPU cooler height is limited to 158mm, and GPU length to 280mm, restricting component choices.
- The backplane requires numerous Molex power connectors, potentially exceeding the supply of typical ATX PSUs.
- Some users report tight cutouts in the fan wall and a 'wiggle' needed for drive connection to the backplane.
- The chassis is not considered quiet by some users, who suggest fan replacement for noise reduction.
Dimension Scores
The chassis provides 24 12Gbps hot-swap bays for 3.5" drives, enabling high-capacity and high-bandwidth storage configurations.
User reports indicate the included 120x38mm PWM fans are not particularly quiet, with some opting for aftermarket replacements.
Constructed from SGCC alloy steel, the chassis offers a sturdy foundation, though some users note tight fan wall cutouts and potential drive connection 'wiggles'.
The backplane's high demand for Molex connectors can complicate cable routing, and the 'rainbow cable' for front panel connections is noted as awkward.
Best For
- Building a high-capacity, petabyte-scale storage server for data-intensive environments.
- Homelab enthusiasts requiring extensive 3.5" drive bays and E-ATX motherboard compatibility.
- Server builds needing hot-swap drive functionality and serviceable cooling during operation.
Not Recommended For
- Users prioritizing quiet operation, as the included fans may be loud.
- Builds requiring CPU coolers taller than 158mm or GPUs longer than 280mm.
- Budget-conscious users who find the chassis's cost high relative to its basic components.
Watch Out For
- The 158mm maximum CPU cooler height means many high-performance air coolers will not fit.
- GPU length is capped at 280mm, which excludes many current generation high-end graphics cards without modification or specific adapters.
- The backplane demands a significant number of Molex power connectors, which can be a challenge for power supply compatibility and cable management.
- Some users report the backplane requires a 'wiggle' to properly seat drives, potentially leading to connection issues.
- The front panel only offers two USB 2.0 ports, which is slow for data transfer and peripheral connectivity.

What Buyers Say
The biggest takeaway from user discussions is the chassis's capacity for 24 hot-swap 3.5" drives, which is a huge draw for anyone building a serious storage server. However, this capacity comes with trade-offs, particularly around power delivery to the backplane, which needs a lot of Molex connectors. Users also point out the limitations on CPU cooler height and GPU length, forcing careful component selection. The included fans are functional but often replaced for quieter operation.
“Man, 24 drives is sick for my Plex server, but seriously, why only USB 2.0 on the front? And I had to buy like three Molex adapters just to power all the drives, what a pain!”
Common Praise
- Accommodates 24 3.5" hot-swap drives, enabling massive storage arrays.
- E-ATX motherboard compatibility allows for powerful server builds.
- Hot-swap 120x38mm fans simplify maintenance without system downtime.
- The 12Gbps backplane supports high-speed data transfer for drives.
- Standard PC components generally fit, offering flexibility for internal hardware.
Common Complaints
- The chassis is considered expensive for its basic construction by some users.
- Limited CPU cooler height (158mm) and GPU length (280mm) restrict hardware choices.
- The backplane requires a large number of Molex power connectors, which can be problematic for PSUs.
- Included fans are often described as loud, leading to user-initiated replacements.
- Front panel only has two USB 2.0 ports, which is outdated for modern use.
Ownership Tips
- You'll probably want to replace the stock fans if you care about noise, they're not exactly whisper-quiet.
- Double-check your PSU's Molex connector count; you might need adapters for all 24 drive bays.
- Fitting a large air cooler or a long GPU will be a challenge, so measure carefully before buying.
- The drive trays can be a bit finicky to seat properly, requiring a firm push or 'wiggle'.
- The front USB 2.0 ports are barely useful for anything beyond a keyboard or mouse.
Frequently Asked Questions
What motherboard sizes does this chassis support?
It supports E-ATX motherboards up to 12" x 13", as well as standard ATX (12" x 9.6") and Mini-ATX (11.2" x 8.2") boards.
How many hard drives can I install?
The chassis is designed to support up to 24 3.5-inch 12Gbps hot-swap SATA/SAS drives.
Are the fans loud?
Some users have reported that the included fans are not the quietest, and some have opted to replace them for reduced noise levels.
What kind of power supply does it use?
It supports standard ATX power supplies, but be aware that the 24-bay backplane requires a significant number of Molex power connectors.
Can I install a large graphics card?
The maximum GPU length supported is 280mm. Some users have managed to fit larger cards like the RTX 4090 with specific power cable adapters, but it requires careful planning.
Buying Guide
When looking at a server chassis like this, you're not just buying a box; you're buying a foundation for your data. The number of drive bays dictates your storage capacity, and hot-swap means you can replace drives without powering down. E-ATX compatibility is crucial if you're planning on using high-end server motherboards with lots of CPU cores and RAM. Cooling is also key, as 24 hard drives generate a lot of heat.
24 3.5" 12Gbps Hot Swap Bays
This means you can install up to 24 standard desktop hard drives, and the 'hot swap' feature lets you pull out a faulty drive and put in a new one while the server is still running, like changing a lightbulb without turning off the power. The '12Gbps' refers to the speed at which data can be transferred to and from each drive, which is fast enough for most modern hard drives.
E-ATX Compatible
E-ATX is a larger motherboard size, typically found in high-performance workstations and servers. If your motherboard is E-ATX, it usually means you have more CPU sockets, more RAM slots, and more PCIe expansion slots for things like RAID cards or network adapters. This chassis can handle those bigger boards, giving you more computing power options.
3X 120x38mm PWM Fan
These are the fans that keep your drives and components cool. '120x38mm' means they are 120mm wide and 38mm thick, which are typically more powerful than thinner fans. 'PWM' (Pulse Width Modulation) means their speed can be controlled by the motherboard, allowing for quieter operation when temperatures are low and higher airflow when things heat up.
Alternatives
If this chassis doesn't fit, search for rackmount cases with higher CPU cooler clearance (e.g., 165mm+) or longer GPU support (e.g., 300mm+), and consider models with more modern front panel I/O like USB 3.0 or 3.1.
