Yea, make sure you've discharged any static electricity on you before touching any of the components, and periodically make sure of that during the process. Don't do the build while standing on carpet, too
While I'm at it:
- make sure your hands are
clean. No grease. Minimal dust, etc.
- Try to find a surface with plenty of room to work so components don't get near the edge (risk of falling off), don't have very far to fall if they do fall off, and people won't be walking through (i.e. not the floor).
- Apply only as much force as necessary to fully seat components (be particularly careful with the CPU, it's relatively easy to bend a pin and brick it, and often places won't take returned CPUs that have physical damage)
- make sure the cpu heat-sink is properly coated with the heat transfer material (goo) that comes with it (unless you got some artic silver or whatnot to use instead), and that it and the cpu fan unit are properly seated and hooked up before applying any power to the unit. cpu running without heatsink = permanently damaged cpu in a very short period of time.
And in general use common sense, follow directions, and be careful, of course, those are just the things that stick out in my memory (no pun intended)
