Custom-built desktop gaming PC

This item appears to be a mid-to-full tower desktop computer assembly, stylistically consistent with modern 'gaming' PCs. The external chassis is finished in matte black and features an integrated vertical RGB LED strip on the front panel, which displays a rainbow gradient spectrum. The side panel is transparent (likely tempered glass or acrylic), revealing internal components illuminated by multiple RGB-lit fans. A rear exhaust fan and a central CPU cooler fan are visible, both emitting multi-color light. A dedicated graphics card is mounted internally, bearing a legible 'GEFORCE RTX' mark on the side and 'RTX' on the backplate, suggesting the presence of an NVIDIA-based chipset. The lower-front exterior of the case bears a small white logo reading 'BASE TECH' alongside a numerical mark '10'. The system is powered on, as evidenced by the active lighting and connection to a black power cable extending across a light wood-grain floor. The overall aesthetic is typical of early-to-mid 2020s consumer technology. Without physical disassembly and software verification, specific hardware specifications and individual component brands remain unverified hypotheses.

I have examined the images of the desktop gaming PC, which appears to be a mid-to-high level custom build consistent with consumer electronics from the early 2020s. Based on what I can see, the chassis bears a mark reading 'BASE TECH 10' and the internal graphics card displays branding consistent with an NVIDIA GeForce RTX series chipset. However, I cannot verify the specific model of the GPU, CPU, or internal storage from a photo, as markings can be misleading or external plates can be swapped. The value estimate of $500 to $850 is based on the hypothesis that the system contains mid-range components such as an RTX 20-series or 30-series card. The condition appears fair with active RGB lighting, though I cannot verify functional stability or internal dust accumulation. The market for used gaming PCs is highly volatile; demand is driven by the specific performance tier of the hardware. To confirm this value, a physical inspection is required to run diagnostic software and verify the exact specifications of the motherboard, processor, and GPU. If the internal components are found to be older legacy hardware housed in a modern case, or 'in the style of' a high-end gaming rig without the corresponding performance, the value could drop significantly to the $200 - $300 range. Conversely, if the system contains top-tier verified components, the value could exceed the current estimate. Further verification via BIOS screenshots or documentation is recommended.
