Specs: Case: Metalfish T40 CPU: Ryzen 7 2700 Memory: 8GB SSD: 256GB M.2 PCIe Graphics: GTX 1660 Super 6GB OS: Windows 11 Home (activated) Accessories: Power cable Used for several months, operation confirmed. Recently passed a 24-hour FF benchmark test. I selected a CPU cooler and graphics card that fit perfectly in this case. I built this to create an ultra-compact gaming PC with a built-in graphics card, but I have other PCs, so I'm selling this one to someone who wants it. Important notes: The power supply is 400W, but the recommended power supply for the 1660 Super is 450W. There have been no issues with slow performance or instability. The graphics card fan makes a rattling noise at low speeds, possibly due to the vertical mounting. The PCIe extension cable is 50cm long and not the one that came with the case. Because it's a small case, the graphics card fan noise leaks out directly when under heavy load, which may be noticeable. The motherboard is a Mouse Computer OEM, so the Mouse logo appears at startup, but there are no operational issues. The CPU and other components are officially supported by Windows 11. With the Ryzen 2700 + 1660 Super, games like Fortnite should run smoothly. Monster Hunter may require lowering the graphics settings. You can return the PC if it doesn't boot into Windows or if the FF benchmark doesn't complete after arrival. However, since I have thoroughly tested the operation, the buyer is responsible for all return shipping costs, regardless of the reason.
