I'm building my first PC and want to avoid damaging the components with electrostatic discharge. There's a metal heater nearby, but it's several meters away, so I'm concerned that walking back and forth could create more static. I have a Brennenstuhl Premium-Protect-Line surge protector plugged into a wall outlet and was wondering whether touching its metal case would discharge me. Would touching the grounding pin in one of its Type E sockets be a reliable alternative? Since ESD isn't visible, I'd also like to know what practical precautions are enough during assembly. I'm planning to handle a Ryzen 7 9800X3D and Radeon RX 9070 XT, so I'm especially cautious about protecting the parts.

ESD is worth being sensible about, but it’s usually less dangerous than first-time builders fear. Assemble the system on the motherboard box or another hard, non-carpeted surface, handle boards by their edges, and avoid touching contacts, chips, solder joints, or connector pins. Ground yourself before picking up sensitive parts, then work normally.
You don’t need to walk back and forth to a heater or remain attached to ground while assembling. If you want extra reassurance, an inexpensive antistatic wrist strap connected to a verified protective-earth point is reasonable. Also avoid synthetic clothing and carpet if possible, and keep the component packaging nearby until each part is ready to install.
If the outlet is properly grounded, touching the exposed grounding pin should discharge you. Touching the surge protector’s metal case may also work if that case is electrically connected to protective earth, but you shouldn’t assume that without testing it. The safest simple option is to plug in the PC power supply, leave its switch off, and briefly touch its unpainted metal housing—provided the outlet is correctly wired and grounded.
A basic outlet tester can check the socket, and a multimeter can verify continuity between the surge protector’s metal case and the earth pin. You only need to ground yourself once after moving around, not keep touching it constantly.
Modern components also include some protection against static, so one careful discharge and good handling habits are generally enough. There’s no visible sign that you’ve discharged, but the brief contact with ground is all that’s needed.
