I'm thinking about building a desktop PC again, but it has been about 17 years since I put one together. I'm sure component selection, pricing, and the buying process have changed quite a bit. Is building part by part still generally cheaper than purchasing a prebuilt system, or are prebuilts now the better value? I know some manufacturers cut corners on parts such as the power supply, motherboard, or memory, so I'd like to prioritize quality and get the best performance for the money. I used to shop primarily through Newegg—are they still a good option, or are there better places and tools for comparing components today?

Newegg isn’t generally considered as strong as it used to be, especially when marketplace sellers are involved. It can still be useful for price checking, but verify who is actually selling and shipping the item. Compare the same parts at several established retailers, and pay particular attention to warranty and return policies.
A nearby Micro Center can make building much cheaper because of its bundle deals, especially for a processor, motherboard, and RAM. If you don’t have one nearby, check comparable bundles from other retailers and watch memory prices carefully. Used RAM can sometimes save money, but buy from a reliable seller and test it when it arrives.
There isn’t one universal answer anymore. Some prebuilts are genuinely good deals, while others save money by using weak power supplies, limited motherboards, or hard-to-upgrade cases. Compare the exact parts and total price against a custom build before deciding. Building yourself still gives you better control over quality, but current memory and storage prices can make a prebuilt surprisingly competitive.

Unfortunately, there isn’t a Micro Center close enough for me to use, so I’ll compare online bundles and probably stick with new parts unless the savings are substantial.
