Small cases with M-ATX motherboards are sufficient to fulfill the expansion requirements of the majority of gamers. In the realm of compact case designs, M-ATX cases have become trendy for relocating the power supply to the front, utilizing a hanging design. This approach allows the small M-ATX chassis to maintain a reduced footprint while still offering ample space for graphics cards, cooling systems, and storage devices.

The FSP CST360 compact case, available in black and white, features a completely meshed front door panel and top surface, ensuring an effective cooling airflow. Its dimensions of 428 x 220 x 381mm make it smaller compared to standard ATX cases, yet it still supports Micro-ATX and Mini-ITX motherboards and has room for 5 PCIe cards.

For the CST360, it’s advisable to pair it with a short FSP power supply of 150mm in length in the front. This configuration permits the installation of graphics cards up to 370mm long, including the substantial RTX 4090. The CPU tower fan height can be up to 165mm, and there are slots for six 120mm fans, with the front and rear fans already pre-installed.

While the case only supports a 240mm radiator for integrated water cooling on the top, this is a typical limitation for compact cabinets. In terms of storage, there’s room for two 3.5″ and three 2.5″ devices. Along with the M.2 expansion capability on the motherboard, this layout can accommodate the installation needs of most players.

The internal layout of the FSP CST360 chassis features a front power supply design, and as such, there’s a removable baffle on the right front with two spaces for 2.5” devices on top. Removing this baffle allows full visibility of the interior space.

The CST360 offers ample upper room to accommodate 240mm water cooling or a pair of fans. There’s also enough space in the lower part to fit two additional 120mm fans. With sufficient openings designed for routing power cables, players are afforded an excellent opportunity for neat cable management in their DIY assembly.

The front door panel and upper mesh top cover of the chassis can be taken off directly, but since the front I/O is located on the door panel, care must be taken with the wiring when disassembling this part. Additionally, a 120mm fan is already pre-installed at the front, so there’s no need to remove the front door panel for installation.

Regarding the bottom of the case, it comes with a magnetic filter and offers space to accommodate cooling for two 120mm fans.

FSP CST360(B) assembly sharing/ Suggest FSP 15cm power supply, install fan below

The FSP CST360 features a front power supply design, and due to the relationship with the front pre-installed fan, the power supply length must not exceed 15cm. Thus, it’s advisable for users of this case to pair it with an FSP power supply that includes an AC extension cord, which will help avoid any interference issues related to the extension cord’s prefix. For instance, the FSP Hydro Ti PRO 1000W power supply, utilized in this context, is a fitting choice.

On the front baffle, there are two 2.5” installation slots. However, since the power supply is situated behind the installation area of the upper slot, managing SATA cables and power cables in that space can be relatively challenging. Therefore, it’s recommended to initially install devices in the lower space. If a second 2.5” device is to be used, it can be mounted in the installation area above the baffle.

The 2.5” installation area located above the baffle offers limited cable management space, as it is situated close to the power supply.

The 2.5” installation space below has a better cable management space.

The actual assembly process of the FSP CST360 is relatively straightforward. By ensuring compatibility with the power supply space and adhering to the installation order of motherboard > power supply > connecting the power cable, chassis cable > storage device > radiator > graphics card, users can enjoy a satisfying and smooth DIY installation experience.

Summary and heat dissipation test

The FSP CST360 offers impressive expandability within its compact M-ATX form factor, but this is contingent on utilizing the “ATX 15cm PSU” component. While the CST360 can accommodate a longer power supply, doing so would necessitate sacrificing the front 120mm installation spot and reducing the length allowance for the graphics card.

To ensure optimal expansion compatibility, the specifications for the CST360 prioritize the use of FSP’s proprietary 15cm long power supply. This provides compatibility with a CPU tower fan height of 165mm, graphics card length of 370mm, and top-mounted 240mm integrated water cooling, satisfying the needs of most players.

For storage devices, the recommended approach is to utilize the 3.5” HDD space at the rear and the 2.5” SSD space under the left side of the chassis. If more storage is required, the 3.5” HDD can also be placed in the left front right bottom of the chassis, with an additional 2.5” SSD atop the baffle. However, these placements require a certain level of DIY cable management skills.

In practical testing with an i5-13600K fixed at P-Core 5GHz and E-Core 3.9GHz, PL Off, using the Scythe SCFM-3000 dual-tower dual-air radiator, CPU temperature reached 99°C under Cinebench R23 multi-core burn-in, whereas in the 3DMark Time Spy Stress Test simulating gaming conditions, CPU was at 77°C and GPU at 74.2°C.

The observed performance is within acceptable ranges, especially considering that the Scythe SCFM-3000 tower fan previously tested at a lower limit of around CPU 180W for heat dissipation. However, for enhanced cooling within the CST360, adding a 120mm intake fan both at the top and bottom of the case would be beneficial. This would create separate upper and lower cooling zones divided by the graphics card, each with its own intake fan, which would lead to improved heat dissipation during gaming.

In Taiwan, the black version of the FSP CST360 is priced at only $1,790, with the white model costing $100 more. For enthusiasts of M-ATX small and mid-sized cases, this price point represents good value for money. The design of the CST360, with its full network opening, is both neat and appealing, offering simplicity with a touch of elegance.
