Design and Build
The HP. OMEN 45L GT22 employs a full-metal frame with tempered glass panels, a common aesthetic in modern gaming desktops that showcases internal components and RGB lighting. A notable design feature is the tool-less entry, which should simplify access for basic upgrades or maintenance. The case includes four RGB lighting zones, with customization managed through the OMEN Light Studio software, allowing for synchronized lighting effects.
Physically, the tower measures 21.85 x 8.03 x 18.5 inches and weighs 49.8 pounds, indicating a substantial footprint that requires a dedicated space. The use of tempered glass, while visually striking, necessitates careful handling to prevent scratches or damage. The overall design prioritizes both showmanship, with its RGB and glass, and claimed practicality through the tool-less design and internal layout that accommodates the OMEN Cryo Chamber cooling system.
Performance and Features
Processing and Graphics Power
The core of the system is the Intel Core Ultra 9 285K processor, a 24-core chip with a maximum turbo frequency of 5.70 GHz and an integrated AI Boost NPU. This hardware is specified for handling complex workloads in gaming, photo editing, and video editing. It is paired with a substantial 64GB of DDR5 RAM running at 5600 MHz, which is far above typical gaming requirements and suggests a focus on heavy multitasking and content creation. The graphics are driven by the NVIDIA GeForce RTX 5070 with 12GB of GDDR7 memory, a card designed for high-resolution gaming and rendering tasks, supporting up to 4K resolution via its HDMI and DisplayPort outputs.
Cooling and Acoustics
A key selling point is the OMEN Cryo Chamber liquid cooling system. This solution combines an AIO liquid cooler with case fans to manage heat from the high-power components. Liquid cooling is generally more effective at dissipating heat from concentrated sources like CPUs and GPUs compared to air alone, which can help maintain higher performance levels during extended gaming or rendering sessions by reducing thermal throttling. The manufacturer does not provide specific data on noise levels or thermal benchmarks.
Connectivity and Expansion
Connectivity is a strong suit for this desktop. The rear panel offers a versatile array of ports: one 40 Gbps Thunderbolt 4 USB-C port (supporting DisplayPort Alt Mode), one 10 Gbps USB-C port, two 5 Gbps USB-A ports, and four USB-A 2.0 ports. For display output, it provides one HDMI and three DisplayPorts from the graphics card. Network options include Gigabit Ethernet, Wi-Fi 6E, and Bluetooth 5.3. For expansion, the system has available PCIe slots (one x16 and one x4) and additional M.2 slots for SSD storage, supporting future upgrades.
Software and Security
The desktop comes with Windows 11 Pro pre-installed, which includes features like BitLocker encryption and Remote Desktop, offering more management and security options than the Home edition. It also includes integration for AI Copilot. The OMEN Light Studio software provides control over the RGB lighting system. The manufacturer does not list any additional proprietary security software beyond what Windows 11 Pro provides.
Setup, Support and Ownership
Setup is described as straightforward by some owners, with the system including a keyboard, mouse, and power cable. The tool-less case design should facilitate adding more storage or RAM, though the liquid cooling system may complicate more involved upgrades for inexperienced users. The product includes a 2-year warranty provided by Techno Intelligence, along with free tech support. It is advisable for owners to check for BIOS and driver updates from HP to ensure optimal performance and stability, especially for newer components like the Intel Core Ultra 9 processor.
Potential owners should be aware of the system’s power requirements, though the specific power supply wattage and efficiency rating are not listed by the manufacturer. The high component density suggests significant power draw under load. The tempered glass panels require careful cleaning to avoid scratches.

What Owners Say
Owner feedback presents a mixed picture that is important to contextualize with the overall rating distribution. The aggregate rating is 3.8 out of 5 stars. Positive reviews highlight the system’s powerful performance, aesthetic appeal, and smooth setup process, with one owner calling it “beautiful” and recommending the purchase. Another expressed being “sumamente contenta” (extremely happy) with the PC.
However, critical reviews point to significant quality control and support issues. One owner received a unit with a faulty hard drive that failed diagnostics and experienced a broken shipping lock, which damaged the case, making the glass door difficult to open and close. They also reported slow communication from the seller regarding a replacement. Another detailed a more severe ongoing issue with a different OMEN 45L model (featuring an RTX 5090), having sent the unit for repair twice for the same unresolved problem, spending months dealing with support instead of using the computer. This underscores the importance of thoroughly testing the system upon arrival and being aware of the warranty process.

Who Should Buy It (and Who Should Skip It)
The HP. 45L GT22 is a compelling option for gamers and content creators who want a top-tier, pre-built desktop with minimal assembly fuss. Its specification sheet is ideal for someone editing high-resolution video, working with complex 3D models, or gaming at maximum settings who also values the visual appeal of a well-lit chassis. The inclusion of Windows 11 Pro and Thunderbolt 4 also makes it suitable for users with professional workflows that require those features. For those building a complete setup, pairing this with one of the best ultra-wide monitors could create an immersive workspace.
This desktop is not the best choice for buyers who prioritize a small form factor, extremely low power consumption, or who are on a tight budget. More importantly, those who are risk-averse regarding potential hardware defects or who need guaranteed, rapid support resolution should carefully consider the mixed owner experiences. Users who enjoy the process of selecting every individual component themselves would be better served with a custom build.

Final Verdict
The HP. OMEN 45L GT22 Gaming Desktop PC presents a formidable package of cutting-edge hardware. The combination of the Intel Core Ultra 9 285K, 64GB of DDR5 RAM, an RTX 5070 GPU, and a dedicated liquid cooling system positions it as a high-performance machine capable of tackling the most demanding games and creative applications. Its design, with tool-less access and extensive RGB lighting, and its connectivity, led by Thunderbolt 4, add significant practical and aesthetic value.
However, the decision to purchase cannot be based on specs alone. The owner reviews highlight a tangible risk of receiving a unit with quality control issues, ranging from minor cosmetic damage to major component failure. Furthermore, experiences with the support process for repairs or replacements appear inconsistent. Therefore, while the HP. 45L GT22 has the raw potential to be an excellent desktop, prospective buyers should purchase from a retailer with a robust return policy and be prepared to test the system comprehensively upon arrival to ensure they receive a fully functional product.
