I built a new PC and tested it successfully before doing the final cable management. While rearranging the cables, I wasn't grounded and felt either a small shock or a sharp sting from one of the solder points. I was wearing Crocs, which made me worry that I had accumulated static electricity. After reading about latent ESD damage—where a discharge might weaken a component without causing an immediate failure—I'm concerned the system could develop problems months later. The PC currently works normally. Is latent ESD damage a realistic concern with modern consumer PC parts, or am I overthinking this?

If the PC is working normally, there probably isn't a reason to rebuild it. A discharge strong enough to cause immediate damage will often result in a component not working at all, and modern PC hardware includes a fair amount of ESD protection. The sensation may also have been a sharp solder joint rather than static electricity.
Latent ESD damage is technically possible, especially with sensitive electronics, but it isn't something that commonly happens from casually touching parts during a PC build. Components generally tolerate more abuse than people expect. Touching the metal case before handling hardware and holding parts by their edges is usually sufficient for a normal home build; a wrist strap is extra caution, not a requirement.
Don't force or repeatedly handle the components, avoid touching contacts and circuit traces, and discharge yourself against the case before working inside. Beyond those basic habits, there is no indication that your working PC has been secretly damaged. If something was actually shorted or destroyed, you would generally notice a failure during testing rather than months later with no other symptoms.
In professional electronics manufacturing, grounding procedures are taken seriously because the equipment can be expensive and repeated exposure can matter. For a one-off consumer PC build, though, the practical risk is much lower. It is still good practice to ground yourself before touching components, but wearing plastic-soled shoes once does not mean the entire system needs to be replaced.
That makes sense. I was mainly worried because I had read that a part could be weakened without failing immediately, but the computer is still working normally.
