The RAM, Ethernet, 10/100BaseT, and internal IDE hard disk

Caution:
Static electricity can destroy electronic components,
such as your controller board, SODIMMs, firmware,
hard disk, and Ethernet board. Use an anti-static
wristband or touch an unpainted metal surface to
eliminate static electricity before working with boards
and upgrades; also, always hold boards and upgrades by
their edges and avoid walking on carpeted areas.
