Those things usually come with your case in a bag - If I'm not mistaken, there are different kinds, depending on the case you are using - I've used different cases throughout the years and found that the ones from other cases might not fit well on my newer case so be careful.
Try Microbytes, ask the service department, bring your case and they might be able to find you some. You can also order those online as well.
If you call micro, make sure you ask for service - don't ask a regular sales guy, they might not know what a standof is LOL
I think I'll try giving microbytes a try on the weekend
486: thanks but I would like to pick these up locally since I just need them to get this build done.
I too had some spare ones, but used them on my other systems.
Let me know if Microbytes has some - I do recall another store carying them, I'm not sure if it was Addison or Maddison, they have all kinds of little gadgets, and I recall seeing somewhere those standoffs - I'll look around see if I can find something.
