When the budget is tight, choosing hardware configurations can be really frustrating, especially for components like GPUs, RAM, and SSDs that are notorious for price hikes. Are there any general purchasing strategies? For example, which parts should we prioritize to save money on, how to avoid high markup periods, or reliable ways to assess second-hand markets? How do you guys usually plan your builds?
What are some good ways to choose accessories on a tight budget?

It sounds a lot like my past experiences with smart home device purchases and the pitfalls I've encountered. When the budget is tight, I prioritize stability and cost savings by treating core accessories like an "IoT gateway." For example, when I first built a NAS, I chose a relatively cheap 500GB SSD (a hot value-for-money option at the time) and went with a second-hand Intel NUC from an enterprise channel for the motherboard. I skipped high-risk options like standalone GPUs and instead went with a Raspberry Pi + low-power display combo as a temporary solution.
As for second-hand channels, I usually follow the same approach as when buying UPS backup batteries for smart door locks: I prioritize official refurbished products (like those from JD.com's "Joybuy" section) and then consider industry-certified enterprise-grade second-hand items (for hard drives, I often go for surplus disks from Gen8 servers). For evaluation, I look at failure rate statistics for network devices: I run a 3-day full-load test, and if anything goes wrong, I return it immediately. This approach is much more reassuring than blindly chasing the latest components.
