When looking for an impressive rack-mountable enclosure, the only consideration is the amount of space required for your specific hardware. Rackmount PC cases with tough chassis can be used as a dedicated server, a durable home entertainment center, a secondary PC for small businesses, or a workstation in a compact horizontal chamber for rough usage, such as a test bench computer for testing different hardware equipment.

Rackmount PC cases typically have room for multiple drive bays and support a variety of large and small components. They are intended for professional workstation builds and minimalist servers that need to be organized and portable for traveling. Their unbreakable construction and sheer toughness come at the expense of a lackluster appearance with no lovely curves, no glass window panel, and, most importantly, no RGBs like best PC cases.

Rosewill 4U Rackmount Server Case, Model RSV-R4100U
Best Professional Rack Mount Server Casing
SPECIFICATIONS
Motherboard Support: SSI CEB, EATX, ATX, Micro-ATX, | Card Supported: LSI SAS Raid controller, Upto 300mm GPU (11.8 inches) | Storage Support: Total (7), 7x 3.5” 2x 5.25” bays | Included Fans: (3) 2x, 80mm, 1x 120mm | Dimensions LxWxH: 25 x 21 x 11.7 inches |
Glorious Model RSV-R4100U, Rosewill 4U Rackmount Server Case is ideal for server management looking for a best-in-class computer chassis for professional jobs with no compromise on strength, lightweight, and practical benefits, such as wall mount capability, fit under the desk or fit in a server room without being wasted on fancy design aesthetics like PC cases for watercooling.
The sturdy metal foundation is excellent with a 17.8-inch depth to support compatibility for the biggest of SSI CEB motherboards and can be as simple as an ATX system with either standard or Micro-ATX motherboards. It has true server benefits with seven 3.5-inch HDDs and two 5.25-inch HDD bays, but what interests me about this case is the ability to mount a full-size RTX 4080 GPU while still breathing efficiently.
We like its material and build quality, which doesn’t feel cheap, but rather sturdy. Other than I/O is a bit minimalist with 2 USB 3.0 and indicators. In our experience, it was the easiest rackmount PC chassis with standoffs and screws for loading everything and transferring with minimal fuss. And because this is a fairly organized and large chassis, it can have plenty of upgrades, and the three pre-installed fans with accessible filters, make a difference in better heat management.
Chenbro Rackmount 4U Server Chassis RM42300-F
Biggest 4U Rackmount PC Case
SPECIFICATIONS
Motherboard Support: SSI CEB, EATX, ATX, Micro-ATX, | Card Supported: 300mm Large GPU (11.8 inches) | Storage Support: Total (7), 4x 3.5” 2x 2.5” bays | Included Fans: 1x 120mm | Dimensions LxWxH: 16.93 x 17.52 x 6.93 inches |
Chenbro Rackmount 4U Server Chassis RM42300-F is a high-quality Rackmount case for workstation builds and creating an organized home and office PC that is always ready to ship with practical support anywhere you move. It can be built into an ATX or EATX system, and a 1.2mm SGCC metal sheet material chassis is built to last a long time.
Despite a single pre-installed 120mm fan, the case has three additional unpopulated fan bays for 80mm fans. If looks aren’t a major issue, this is a fairly standard rackmount case that ships with a single drive bay but can support up to nine with additional hot-swap drive caddies if you’re willing to send the money.
The power supply brackets are adjustable for 9 different positions, and the ability to install a full-size 300mm GPU and 120mm CPU cooler radiator instead of 5.25″ bays is a nice touch. The biggest quirk of the Chenbro 4U case is most universal rails/shelves are too long for its short chassis, but the light weight of a smaller system allows more permanent installation by simply screwing the case onto the rack or under the desk as you prefer.
Rosewill 4U RSV-L4000U 11 Bay Rackmount Server Rig
Best Rack Mount Gaming PC Case
SPECIFICATIONS
Motherboard Support: Micro-ATX, ITX | Card Supported: 300mm Large GPU (11.8 inches) | Storage Support: Total (11), 8x 3.5” 3x 5.25” bays | Included Fans: Total (7), 5x 120mm, 2x 80mm | Dimensions LxWxH: 31 x 23 x 11 inches |
When money is tight, the RSV-L4000U Rosewill 4U Rackmount Server Rig is another fantastic option. In comparison to its larger twin, the RSV-R4100U, which is our favorite (first pick) from selection to be a custom rig or a great server PC, the current Rosewill 4U RSV-L4000U has some advantages for some folks.
This case adds value to a good server rig and can be an HTPC with evaluated high-end components. The 25-inch depth provides a nice playground for a cool system with up to 8 fans pre-installed, ensuring that no overheating occurs during usage, and shows great potential for powerful components.
The large front mesh is a distinguishing feature that contains a security lock, ensuring no one can access your PC until the key is present. This function truly signifies a personal computer from the rest of Horizontal PC cases. Another noticeable advantage is the 7 expansion slots, which we believe are well worth paying for given how well they will be used in practice.
RROYJJ 4U Rackmount Server Case
Best Rackmount PC Case with Most Storage
SPECIFICATIONS
Motherboard Support: EEB, CEB, EATX, ATX, Micro-ATX | Card Supported: Multiple 400mm large GPUs | Storage Support: Total (24), 3.5” and 2.5” compatible | Included Fans: Total (5), 3x 120mm, 2x 80mm | Dimensions LxWxH: 32.68 x 22.44 x 9.84 inches |
If a big server case is your desire, I cannot recommend anything other than the RROYJJ 4U Rackmount Chassis. Not only does it worth a large server replacement but can be a great gaming PC with a modern GPU, a custom water cooling system, and plenty of storage.
To introduce you to the most extreme chassis for building an unrivaled rackmount PC, we hand-selected the RROYJJ 4U Rackmount Server Case. It’s more of a unique PC case than an HTPC, so it’s not for everyone. Thus, if you require a sizable chassis for big servers that really can accommodate 24 Hot-Swappable SATA and SAS Disk Bays, it is an appropriate choice for both personal and professional use.
It features a huge deep room that is compatible with full-size EEB, CEB, ATX, and Micro ATX motherboards. However, it is not a cheap case, costing $690, but no compromise on quality, and feels strong in every way. The only negative is the mediocre 120mm cooling fans are a little noisy.
SilverStone Grandia SST-GD11B Compact (HTPC)
Best Rack Mountable HTPC Case for Gaming and Media
SPECIFICATIONS
Motherboard Support: SSI-CEB, ATX, Micro-ATX, ITX | Card Supported: 340mm large GPUs | Storage Support: Total (3), 3.5” and 2.5” compatible | Included Fans: Total (2), Supported 4x 120mm, 2x 80mm | Dimensions LxWxH: 13.57 x 17.33 x 6.93 inches |
In our opinion, the simplest form factor and ready-to-use PC case are for practical individuals. This is true for the SilverStone Grandia SST-GD11B Compact Home Theater PC (HTPC) case, which is an excellent case that is sleek and portable and inspired by a rackmount server chassis for great maneuverability over a lack of tolerance from fragile glass panels, and meaning fewer RGBs.
If you need a practical HTPC chassis similar to our picks for slim ATX cases for a home theater experience, the SilverStone Grandia GD11 is a steal. It costs only $200 for what it provides in terms of desktop PC competitiveness. There is enough room for a 240mm liquid CPU radiator and 340mm extended-length GPU suitable for modern RTX 4000 gaming GPUs.
The dual chamber architecture splits 6 expansion slots up to 13.4 inches long and 5.9 inches in height, which is the most evident advantage. Depending on how you use the space, I feel, its space is sufficient for all AGP video cards, AMR modem sound cards, VESA, PCI network cards, and PCI Express video cards in combination.
Supermicro Rack Mount Server Chassis CSE-505-203B
Slimmest Server Rack PC Case
SPECIFICATIONS
Motherboard Support: Mini ITX | Card Supported: 240mm large GPU | Storage Support: Total (4), 3.5” and 2.5” compatible | Included Fans: Total (2), Supported 4x 120mm, 2x 80mm | Dimensions LxWxH: 17.2 x 9.8 x 1.7 inches |
As expected, Supermicro provides an excellent solution for server builds. This $189 CSE-505-203B Rack Mount Server Chassis features a modest form factor and is reasonably priced for compact and solid build quality. Its ultra-slim form fits neatly into any universal rack.
This Mini 1U chassis is 9 8 inches deep and can accommodate a maximum motherboard size of 6 75″ x 6 75″. Although the quality and materials are excellent, this Supermicro Rack Mount Server Chassis CSE-505-203B has limited storage capacity to 2x 2.5-inch internal HDDs or 2x 3.5-inch HDDs, for which I prefer to use a regular 19-in 3U Rack Drawer unless switching it for the best mini ITX NAS case with swappable drives.
I like that it can utilize a GPU with a length of 64.41mm x 119.91mm for a range of professional applications. Also, you won’t need any additional PSU expenses, this comes with a 200W 80 PLUS Gold Certified Power Supply, however, check for a separate IO plate if you don’t want to leave it open.
Rosewill 2U RSV-Z2600U 2U Server Chassis
Compact Custom Server Casing
SPECIFICATIONS
Motherboard Support: Micro ATX, Mini ITX | Card Supported: 300mm large GPU | Storage Support: Total (4), 3.5” and 2.5” compatible | Included Fans: Total (3), 80mm | Dimensions LxWxH: 15 x 16.9 x 3.5 inches |
The Rosewill 2U Server Chassis RSV-Z2600U sits within a category of well-round Rackmount chassis, built to last and great with storage. The amount of money you will spend is around $170 for a quiet and effective server chassis that comes equipped with (3) front 80mm cooling fans and a PS2 power supply. pre-installed.
This is one of the roomy chassis with 4 internal 3.5″ HDD bays and supports 4 PCI expansion slots with Micro-ATX board, but barely handles standard ATX or EATX, so avoid those for better cable management and everything else.
The chassis features the usual rack case design, but building in it is a breeze and the temperature remains under 50 degrees Celcuos with 3 pre-installed 80mm front cooling fans. However, I’ll not advise populating all 4 low profile Expansion slots with add-on cards for the sake of performance.
iStarUSA Group 2U Compact Rackmount Cabinet D-214-MATX
Best Portable Rack Case for Home Servers
SPECIFICATIONS
Motherboard Support: Micro ATX, Mini ITX | Card Supported: Less than 240mm GPU | Storage Support: Total (3), 2x 3.5” 1x 5.25” | Included Fans: Total (2), Supported 4x 120mm, 2x 80mm | Dimensions LxWxH: 15.5 x 3.5 x 19 inches |
With 2U design preference, the iStarUSA Group Compact Rackmount Cabinet D-214-MATX is one of the company’s best-selling models, more like a minimalist PC case. However, relatively cheap and relies on airflow fans with a sleek skeletal frame that includes a straightforward front panel, 2x USBs, and indicator lights, nothing extra.
Though it seems fairly basic, and thoughtful for an entry-level user whose needs are limited to just 2x 5.25″ external bays, 3x 3.5″ internal bays, quad channel Expansion bays, and quad Expansion slots. The primary missing features are the lack of full-size GPU support and no extra fans. But this does offer what it means, you can build a solid PC for less than $100.
Buying Guide for RackMount PC Cases
Should I Rackmount My PC?
Rack mounting your PC in a rack can optimize your workspace, increase accessibility, and improve cable management. If you have planned rack mounting your rig, it will also provide efficient protection for your hardware, better airflow, and reduced dust accumulation in your workspace.
How Does Rackmount Work?
Rackmount computers are PCs of varying sizes that are stored securely in an enclosure or a “rackmount cabinet.” This protects the computer from outside sources or elements that may cause damage. Rackmount computers are used in various settings, from industrial to office, for multiple applications.
Pros and Cons of RackMount PC Cases
Do Rackmount Servers Need Rails?
It is not safe for servers to stack one on top of the other without their own rails. Rails provide additional support, making it easier to slide servers in and out of the rack for maintenance and upgrades.
How Deep is a Rackmount Server?
The depth of rackmount servers was commonly between 19″ to 24″, which is still used for audio racks. However, the most common depth now is approximately 29″, which is close to all OEM standards. Any depth greater than 29” provides extra support for cable management and additional accessories.
