Im fitting a new ASUS crosshair V formula Z motherboard into my NZXT phantom 410, but I'm missing a standoff, I was going to buy some new ones, however before I do I wanted to check that theyre all the same and I don't need special sized ones or anything like that.

For those wondering these where the ones I was looking at

Actually, motherboard stand-offs have 4 variants which are the most common as far as i know. These variants differ in both stand-off size, meaning there is more or less room for the inner thread that is used and another difference can be the type of thread (6-32 or M3) that is used for the inner thread. The outer thread that is used should always be the same (6-32). The most commonly used length for a stand-off is 6.4 mm (as dictated by the current ATX form factor standard).

The difference in inner thread used (6-32 or M3), is the same difference as the thread that can be used for fitting both 3.5" harddrives and 5.25" bay devices (opticals mostly), where the thread on 6-32 screws for 3.5" mounts are slightly bigger and more crude so to say and M3 is slightly smaller and has a 'finer' thread.

The stand-offs you are linking to are the ones most commonly used nowadays.

Seeing as they aren't that costly and come in a 50-pack the solution should be quite simple. When they arrive check the type of inner thread that is used.
(You can see the difference with your eyes otherwise just gently try and fit a 6-32 screw in there and if that doesn't run in it uses an M3 screw with the 'finer' thread).
If it turns out to be different from all the other ones you used in your build, you could consider replacing all of them so they're all the same (if it matters to you and you're going for a clean build or a casemod or so....)

The longer stand-offs i am talking about were seldomly supplied by manufacturers of non-standard computer cases or sometimes used by OEMs like Packard Bell or Medion.
Also, here's a Wiki article that shows the difference between 6-32 and M3 thread:

Good luck!
