I'm building my first PC and would really like to assemble it myself instead of buying a prebuilt. I like the performance of the PowerSpec G764, but I don't care for its case and would prefer something with a black aquarium-style design, such as the Lian Li O11 Vision. My budget is around $2,200, including Windows, Wi‑Fi, and Bluetooth. I already have a 4K monitor, keyboard, and mouse.
I'd like to play AAA games at high settings and want the system to remain useful for roughly four or five years before needing a major upgrade. The G764 includes a Ryzen 7 9800X3D, Radeon RX 9070 XT, 32GB of DDR5-6000 memory, a 2TB NVMe SSD, and a Wi‑Fi motherboard. I'm having trouble matching that performance with a custom parts list without going over budget. Is it realistic to build something comparable with a better-looking case, or would buying the prebuilt and customizing it later make more sense? I also live near a Micro Center, so local bundle pricing may be an option. I'm still learning about PC parts, so beginner-friendly advice would be appreciated.

The first step is comparing complete parts lists rather than just the headline specifications. The G764 uses a Ryzen 7 9800X3D, RX 9070 XT, 32GB of DDR5-6000, and a 2TB NVMe drive, so a custom build can match it, but the case, power supply, cooling, Windows, and extra fans can quickly consume the remaining budget. Micro Center bundle deals may make the DIY route more competitive. For a 4K gaming system, the graphics card matters most, so I would avoid cutting the RX 9070 XT unless you need room for the case and other parts.
The prebuilt is not automatically a bad choice if its price is close to the cost of the individual parts. You could potentially replace the case later, but first verify that the motherboard, power supply, cooling system, and front-panel connections use standard parts. If you build yourself, choose the case for airflow and radiator or GPU clearance rather than appearance alone. A black dual-glass case with modest green lighting is achievable, but don’t sacrifice the graphics card just to afford a more expensive showcase case.
You can save money by stepping down from the 9800X3D if your games are not especially CPU-heavy. A Ryzen 7 7800X3D, or even a Ryzen 5 7500F, 7600, or 7600X, would still pair well with the RX 9070 XT for 4K gaming and would free up money for the case, a quality power supply, and storage. The 9800X3D is excellent, but at 4K the graphics card is usually the limiting component, so the real-world difference may be small in many AAA games.

That helps. I hadn’t realized how much the case, cooling, and power supply added up once I included everything.
