I'm new to desktop PCs and want one mainly for games such as Infinity Nikki, along with learning video and photo editing. I originally planned to buy a used system because my budget is around $500, but I'm not sure how to judge whether secondhand parts or complete computers are good deals. Would building a PC myself be more cost-effective, or should I focus on finding a used or refurbished system? I'd also appreciate a basic explanation of what parts matter most for gaming and editing.

For your use case, think of the parts this way: the CPU handles general tasks, RAM is temporary workspace, the SSD stores your files and makes the system feel fast, and the GPU does most of the heavy work in games. Video editing can benefit from extra RAM, fast storage, and hardware encoding support, especially from Nvidia or Intel GPUs, while AMD cards can offer strong gaming performance for the money. Start with 16GB of RAM and a 500GB or 1TB SSD, then upgrade later if editing projects become demanding.
You can build something decent with used parts, but you’ll need to compare prices carefully because some sellers ask nearly-new prices for old hardware. A practical target might be a Ryzen 5 5600 or similar CPU, a B450/B550 motherboard, 16GB of DDR4 RAM, an RX 6600-class graphics card, a reliable 550–650W power supply, and an SSD. An older RX 580 can save money, but it uses more power and is much slower. Don’t spend the entire budget on the CPU and forget the power supply, storage, or case.
Before buying anything, watch a complete PC-building tutorial from start to finish. It’s mostly a matter of installing compatible parts and connecting cables, but following along with a guide makes the first build much less intimidating. Make a checklist containing the CPU, motherboard, RAM, graphics card, storage, power supply, case, and any needed fans. Also remember that a $500 budget may need to include a monitor and peripherals, in which case a used complete system becomes even more attractive.
For a $500 total budget, a complete used PC is usually the best value. A new build at that price often means making compromises on the graphics card, storage, or power supply. Look for a system with at least 16GB of RAM, an SSD, and a reasonably modern six-core CPU. For gaming at 1080p, the graphics card is usually the most important part. Test the computer if possible, check temperatures and noise, and avoid listings with vague specifications or no way to verify that the GPU works.
Prebuilt systems are also worth checking right now, especially if there’s a sale or a reputable refurbished option. Compare the exact parts rather than trusting labels like “gaming PC,” and make sure the power supply is from a known brand. Whether you buy used or build your own, 1080p gaming is the realistic target at this budget; newer demanding games may require reduced settings.
