A standoff installed in the wrong place can cause a short and prevent the system from booting.
What will be considered a standoff placed in the wrong position? If I have a spare standoff which I screwed to an unused slot does that count?
That would be a perfect example of placed in the wrong position - you should only use as many standoffs as you have mounting holes on your motherboard, extras are just that - extra. If the extra is under the motherboard somewhere, that is very bad.
Also I read abit about shorts and static: If I dont have an antistatic bag, where is the best place I can put my hardware? What are some good/bad places?
Bad places would be any conductive material (aluminum foil, mylar), cling type plastic wrap
Good places would include the original packaging, other computer hardware packaging, a shoe box or perhaps a cigar box. My preference is old computer hardware boxes (if I don't have the original packaging)
