Warning: My build guide obsession led me to ignore the static wristband dogma... and it worked out fine
Everyone insists on using an anti-static wrist strap, but I found that regularly touching the metal case frame before handling parts was sufficient. I built my entire system on a wooden table in a low-humidity room, and zero components were damaged. The key was avoiding synthetic fabrics and keeping one hand on the case... it saved time and hassle without risking a shock. I even verified the grounding with a multimeter, a step most guides overlook.
Honestly, the wrist strap panic is overblown. I remember reading a breakdown by an electrical engineer on a forum who tested various static prevention methods. He found that grounding yourself to the case, like you did, is just as effective if done consistently. Modern components have better ESD protection than people realize. The key is avoiding high-risk environments, like carpeted rooms with synthetic clothes. Your multimeter check is smarter than most builders who just follow steps blindly.
Used to insist on wrist straps for every PC build. Read that same engineer's breakdown last year. His testing on case grounding convinced me. Now I just tap the PSU before touching anything sensitive. No problems yet.
