Latherial :
im building a computer and i need to know what tools i need for the standoffs and whatever else i would need for assembling the computer
A Philips Screwdriver and some common sense
. Really, that's it!
You may also need some thermal compound if your cooler does not come with it pre-applied. What cooler are you using?
Also, you can get an ESD wrist strap to prevent static discharge from frying your components. However, this is not essential; as long as you don't assemble the PC while standing on carpet, and touch the metal case often while assembling it, you'll be fine.
EDIT: My first link to a ESD wrist strap had some bad reviews, here is a better one...
