XTIA XPROTO-L – How You Can Build an Insane Open Case Gaming PC

This build is nothing like my typical projects—an open-case water-cooled design that doubles as a work of art and a high-performance PC. Its vertical layout not only showcases the hardware beautifully but also contributes to lower noise levels and outstanding thermal efficiency by constantly drawing in fresh air. Let’s delve into the components selected for this unique build, explore the assembly process, and then assess its thermal performance and gaming capabilities.

Parts

CPU:  7800X3D

For the CPU, the 7800X3D is chosen, widely regarded as the premier gaming CPU currently available, boasting 3D V-Cache acceleration for enhanced gaming performance. Its specifications include 8 cores, 16 threads, and a boost clock of up to 5GHz, making it an ideal match for the high-end GPU selected for this build. Priced at $450, it promises exceptional gaming capabilities.

Motherboard: B650I Auros Ultra

The 7800X3D CPU necessitates a new AM5 motherboard, and for this build, the Gigabyte B650I Auros Ultra is chosen. While AM5 Mini-ITX motherboard options are currently limited, future considerations may include an X670 chipset when more choices become available. Nonetheless, the B650I Auros Ultra provides ample features such as numerous USB ports including Type-C, along with WiFi 6E support and a convenient BIOS flashback button.

This motherboard offers extensive storage capabilities, accommodating two M.2 drives under the heatsink—one Gen5 and one Gen4. Additionally, there’s space for an extra Gen4 drive at the back under the backplate, enhancing storage flexibility for the build.

Storage: Generation 4 Samsung 980 Pro m.2 Drive

I’m only utilizing a single 2TB Gen 4 Samsung 980 Pro drive for now. It offers ample storage for my requirements and is notably more cost-effective compared to a Gen 5 drive, which wouldn’t yield substantial gaming benefits over Gen 4.

RAM:  DDR5-6000 Corsair Dominator Platinum

For this build, DDR5 memory is essential. I’ve opted for 32GB of DDR5-6000 Corsair Dominator Platinum RAM. These modules are tailored for AMD setups with an EXPO memory profile, operating at the optimal 6000MHz speed ideal for 7000 series CPUs.

CPU Cooler: NZXT Kraken Elite 240

For the CPU cooler, the choice is the new NZXT Kraken Elite 240. This liquid cooler stands out with its impressive 2.3-inch 60Hz LCD display, offering clear and bright visuals. While in most ITX builds, opting for a cooler with a screen might seem unnecessary, in this setup, it serves as the focal point. With a plethora of customization options for infographics, images, and fan controls, it adds both functionality and aesthetics.

Case: XPROTO-L

Moving on to the case, we have the XPROTO-L, a slightly larger variant of the XPROTO designed to accommodate triple-slot graphics cards and ATX power supplies. While assembly is required for the entire case, XTIA has streamlined the process with excellent organization, including an interchangeable screwdriver with the necessary bits for assembly.

The metal components of the case exude high quality and precision machining, leaving a lasting impression. Let’s begin assembling by placing square spacers into corresponding indents on the backside of the plate and securing them from the opposite side.

Power Supply: Corsair RM850e

To power this build, I’ve opted for the RM850e from Corsair. When selecting an ATX power supply for this setup, it’s crucial to choose one with a height of less than 150mm. Anything taller could pose challenges for cable management and fitting the motherboard securely above it.

It’s highly advisable to invest in flexible cables for this build. XTIA offers custom-length, highly flexible cables specifically designed for this setup, which are chosen for this build. Alternatively, Corsair’s premium-sleeved cables, either included with the SF750 or purchased separately, can also work well. Using standard cables may require bending them in ways that aren’t recommended, leading to a more complicated build process.

GPU: RTX 4090 Founders Edition 

Next, the GPU installation phase arrives, featuring the RTX 4090 Founders Edition. Renowned for its unparalleled performance, this GPU stands in a class of its own, outmatching all others, albeit at a considerable cost and often deemed excessive for typical usage scenarios. Nonetheless, for this top-tier build, combining the 7800X3D with the RTX 4090 promises the pinnacle of current performance capabilities. Securing a Founders Edition can be challenging, with limited drops typically occurring monthly on Best Buy, and rapid sellouts are common. However, this case accommodates GPUs up to 345mm, ensuring compatibility with a wide range of third-party options.

Performance

The performance of this setup is nothing short of extraordinary, effortlessly handling 4K and 1440p resolutions at high and ultra settings without breaking a sweat. Ideally, pairing this powerhouse with a high-refresh-rate 4K display would be the optimal choice, although a high-quality 1440p monitor could also serve well for those seeking uncompromised settings and frame rates.

Starting with Cyberpunk at 4K resolution without DLSS or ray tracing, the system delivers a solid 75-80 frames per second, a commendable experience. Activating ray tracing and DLSS with the RTX 4090 still maintains an impressive 70-80 frames per second with stunning visuals.

For 1440p displays, rasterization performance hits around 140 fps, offering smooth gameplay across various titles. In Hogwarts Legacy, running at maxed-out ultra settings in 4K, rasterization performance exceeds 60-70 frames per second, soaring to over 130 fps with DLSS and frame generation enabled, showcasing the GPU’s prowess.

Temperatures remain well in check, with the NZXT Kraken efficiently cooling the CPU, and the open case design facilitating optimal airflow for all components. In demanding games like Apex Legends at 4K high settings, performance remains stellar at over 150 frames per second, making it more than capable of handling a 240Hz 1440p monitor at max settings.

During extended usage, GPU temperatures average around 62 degrees Celsius, while CPU temps peak at 69 degrees Celsius during intensive tasks, showcasing the robust cooling capabilities of this setup.

This build, focused on gaming excellence, boasts impressive thermals, with the CPU staying at or below 50 degrees Celsius and the GPU hovering around 60 degrees Celsius in demanding scenarios.

With a silent profile in the NZXT CAM software, the system maintains a quiet operation, ideal for immersive gaming sessions. However, it’s worth noting that this build, while delivering exceptional performance, is tailored more towards enthusiasts who enjoy showcasing their hardware and can accommodate an open case design. Although not protective against environmental factors like dust or pets, positioning it in a safe, elevated location can mitigate such risks.

The XPROTO’s build quality impresses with its sturdiness and attention to detail, offering a solid foundation for a high-end build. Flexible power supply cables are strongly recommended for optimal cable management in this open case setup.

While the case, PCIe riser cable, and 240 AIO bracket cost around $185, the entire configuration, including the RTX 4090 and other components, totals at $3,450. However, customization options allow for building a visually stunning rig at varying price points.
