The CiT 4U-500 is a 4U rackmount computer chassis designed for building a rack-mounted PC, home server, storage server, workstation, CCTV/NVR system, or custom rack server. It uses a horizontal rackmount layout instead of a traditional tower case design.

4U refers to the rack height of the case. One rack unit is approximately 1.75 inches, so a 4U case is around 7 inches high. A 4U chassis gives more room than 1U or 2U server cases and can support more standard PC components.

Yes. The CiT 4U-500 is designed as a 19-inch rackmount case. The listed external width is approximately 482mm, which matches standard rackmount chassis width. Always check your rack depth before buying.

The CiT 4U-500 is a 500mm-class rackmount case, with listed external dimensions of approximately 482 x 177 x 501mm. The chassis depth excluding fascia/panels is listed around 455mm. Check your rack cabinet depth and allow space for rear cables and airflow.

It depends on the rack depth. Because this is around a 500mm deep chassis, it may not fit very shallow wall cabinets. Check the usable internal rack depth and allow extra space for power cables, network cables, airflow, and rear clearance.

The CiT 4U-500 supports ATX, Micro-ATX, and Mini-ITX motherboards. It is suitable for standard desktop-style server and workstation builds using common motherboard formats.

No. The confirmed motherboard support is ATX, Micro-ATX, and Mini-ITX. If you need E-ATX, SSI-EEB, or larger workstation/server motherboard support, choose a larger chassis with confirmed compatibility.

Yes. The CiT 4U-500 supports a standard ATX power supply. This is useful because it allows builders to use common desktop PSUs instead of noisy proprietary server power supplies.

No. The CiT 4U-500 does not include a PSU. You will need to purchase a suitable ATX power supply separately based on your motherboard, CPU, storage drives, graphics card, and expansion cards.

The PSU is installed at the bottom section of the chassis. When choosing a PSU, check cable length and connector routing because rackmount cases often have different cable paths compared with tower PC cases.

The CiT 4U-500 supports up to 8 x 3.5-inch internal drives, plus additional external bay options. This makes it useful for storage-heavy systems such as NAS-style builds, backup servers, CCTV/NVR storage, and home lab file servers.

The case supports 2 x 2.5-inch internal drives, with one 2.5-inch and 3.5-inch mounting position listed as shared. This is useful for SSD boot drives, cache drives, or extra SATA SSD storage.

Yes. The case includes 2 x 5.25-inch external bays and 1 x 3.5-inch external bay. These can be useful for optical drives, hot-swap bay accessories, card readers, control panels, or legacy devices, depending on the build.

Yes. The large number of 3.5-inch internal drive bays makes the CiT 4U-500 a practical option for a budget NAS or storage server build. Make sure you choose a motherboard or expansion card with enough SATA ports and plan cooling carefully for multiple hard drives.

Yes. The CiT 4U-500 is well suited to home lab users who want a rackmount chassis that supports standard ATX components, multiple drives, expansion cards, and a normal ATX PSU. It is a practical choice for virtualisation, storage, firewall, backup, or test server builds.

Yes. The internal hard drive capacity and rackmount format can make it suitable for CCTV/NVR recording systems, especially where multiple surveillance drives are needed. Check cooling, drive vibration, SATA port count, and PSU capacity before building a multi-drive recorder.

It can be used for some gaming PC builds, but it is not designed as a gaming case. The GPU clearance is up to 270mm and the CPU cooler height is up to 115mm, so many large modern gaming graphics cards and tall tower coolers may not fit. For high-end gaming builds, check component dimensions very carefully.

The CiT 4U-500 supports graphics cards up to approximately 270mm long. This may fit some compact and mid-size GPUs, but many large triple-fan graphics cards are longer than 270mm and may not be suitable.

Yes. The case has 7 full-size expansion slots, which can support full-height PCIe cards such as graphics cards, RAID/HBA cards, 10GbE network cards, capture cards, and sound cards, subject to length and cooling clearance.

The CiT 4U-500 supports CPU coolers up to approximately 115mm tall. This is lower than many tower cases, so check your CPU cooler height carefully before buying. Low-profile or compact tower coolers are usually safer choices.

Usually not. Many large air coolers are taller than 115mm and will not fit in this rackmount chassis. Choose a low-profile or 4U-compatible CPU cooler that fits within the height limit and can handle your CPU’s heat output.

No. The confirmed specification lists this case as not water cooling ready. It is better suited to air-cooled server, NAS, workstation, or rack PC builds rather than AIO or custom liquid cooling setups.

The CiT 4U-500 is not listed as water cooling ready, and radiator support is not confirmed. If you need 240mm or 360mm AIO support, choose a rackmount case specifically designed for liquid cooling or measure carefully before attempting a custom installation.

The CiT 4U-500 includes 1 x 120mm front fan. The rear has space for 2 x 60mm fans, which are optional and may need to be purchased separately depending on your cooling requirements.

No. The listed cooling support is 1 x 120mm front fan and space for 2 x 60mm rear fans. It does not list top, side, or bottom fan mounting positions. Cooling should be planned around front-to-rear airflow.

Noise depends on the fans and components used. The included 120mm front fan may be quieter than small high-RPM server fans, but adding 60mm rear fans can increase noise if they run fast. Use quality fans and sensible fan curves if low noise is important.

It can be. Rackmount cases often rely on front-to-back airflow and have less vertical clearance for large CPU coolers. For best results, use efficient components, suitable low-profile coolers, tidy cabling, enough intake/exhaust airflow, and avoid blocking rack ventilation.

A typical rackmount airflow plan is front intake and rear exhaust. The included front 120mm fan brings cool air in, while optional rear 60mm fans can help exhaust warm air. Keep cables tidy and avoid blocking airflow across drives, CPU cooler, and expansion cards.

They can, but this depends on drive count, front fan airflow, cable routing, rack ventilation, and room temperature. If you install many 3.5-inch drives, monitor drive temperatures and consider adding rear fans or improving rack airflow if temperatures are high.

Yes. The case includes a lockable front door. This can help protect the power/reset buttons and front drive bays from accidental access in a rack, workshop, office, studio, or shared environment.

The front I/O includes 2 x USB 2.0 ports, along with front panel controls and indicators such as power, reset, HDD LED, and power LED. It does not list USB 3.0 or USB-C front I/O.

No. The CiT 4U-500 lists 2 x USB 2.0 front ports only. If front USB 3.0 or USB-C is important, you may need a separate 5.25-inch front bay accessory or a different rackmount case with modern front I/O.

The confirmed listing describes the chassis and accessories, but rack rails are not clearly listed as included. If you need sliding rails, check compatibility and package contents before ordering, or plan to use a suitable rack shelf.

Yes, many users mount rack cases using front rack ears and/or a fixed rack shelf. Because a fully built system can be heavy, supporting the rear of the chassis with rails or a shelf is recommended for safety and stability.

The listed net weight is approximately 8.1kg, with a gross packaged weight of approximately 9.2kg. The final system will be heavier once the PSU, drives, motherboard, cooler, expansion cards, and cables are installed.

The case is listed with a 0.7mm SECC metal body and a 1.5mm SGCC metal front bezel. It is designed as a practical rackmount chassis rather than a tempered-glass gaming display case.

No. The CiT 4U-500 has a blank metal side/top panel style typical of rackmount cases. It is designed for rack installation and component access rather than RGB display or showcase builds.

Yes, it can be suitable for studio users who want a rack-mounted PC alongside audio interfaces, preamps, mixers, or effects units. For studio use, pay close attention to fan noise, vibration, drive noise, and rack ventilation.

Yes. The metal rackmount design, lockable front door, standard ATX support, and multiple drive bays make it suitable for many workshop, industrial, lab, and control-room style PC builds where a rack-mounted chassis is preferred.

Yes, it can sit on a desk or shelf, but it is larger and heavier than most desktop tower cases. It is mainly designed for rack use, so the layout, front I/O, airflow, and access style are different from a normal tower case.

It is reasonably practical for a rackmount case because it supports standard ATX parts, but it may feel different from a tower case. Cable routing, cooler clearance, drive installation, and airflow planning need more attention because rackmount cases have a horizontal layout and limited vertical clearance.

Yes. You can use a standard desktop ATX, Micro-ATX, or Mini-ITX motherboard with a compatible desktop CPU. Make sure the CPU cooler fits within the 115mm height limit and that the PSU has enough power for the system.

Only if the server motherboard fits the supported ATX, Micro-ATX, or Mini-ITX mounting pattern and dimensions. Larger server boards such as SSI-EEB, E-ATX, or proprietary layouts may not fit.

Yes. The 7 full-size expansion slots make the case suitable for PCIe RAID cards, HBA cards, 10GbE network cards, and other expansion cards. Check card length, airflow, and cable routing, especially if using many internal drives.

Yes. The CiT 4U-500 can be a good budget chassis for TrueNAS, Unraid, Proxmox, or other home server platforms because it supports standard PC hardware and multiple 3.5-inch drives. Make sure your motherboard, HBA/SATA controller, RAM, network card, and cooling plan match your server workload.

The case includes internal and external drive bays, but it is not clearly listed as having built-in hot-swap backplanes. If you need hot-swap drive access, consider adding compatible 5.25-inch hot-swap bay modules or choosing a chassis with built-in hot-swap bays.

Listings highlight the rackmount design, lockable front door, drive bays, and cooling positions, but dust filter details may vary. For rack systems, clean the front intake area and fans regularly to maintain airflow and reduce dust build-up.

Choose the CiT 4U-500 if you need a rackmount system, many drive bays, and standard ATX hardware support in a rack. Choose a tower case if you want easier cable management, taller CPU cooler support, better gaming GPU clearance, more modern front I/O, or quieter airflow options.

The CiT 4U-500 is easier to build in than many 2U cases because it offers more vertical space, standard ATX PSU support, full-size expansion slots, and more cooling flexibility. A 2U case saves rack space but usually requires lower-profile components and can be louder due to smaller fans.

The CiT 4U-500 is best for users building a budget rackmount PC, home server, NAS, backup server, CCTV/NVR recorder, studio rack PC, or home lab system using standard ATX, Micro-ATX, or Mini-ITX components.

This case is not the best choice if you need front USB-C, USB 3.0 front ports, E-ATX motherboard support, large modern GPUs over 270mm, tall CPU air coolers over 115mm, confirmed liquid cooling support, or a showcase gaming case with tempered glass and RGB lighting.

Before buying, check your rack depth, motherboard size, ATX PSU length and cables, CPU cooler height, GPU length, number of hard drives, SATA/HBA requirements, fan noise expectations, rack rail or shelf support, and whether USB 2.0 front ports are suitable for your setup.
