I have an Antec Solo case, which has a spare 5.25" drive bay.

I want to put a 3.5" hard drive into the 5.25" bay, so I bought a 3.5" to 5.25" adapter.

But, the adapter does not come with drive rails, and I do not have any spare for the case.

So, I need a pair of drive rails for a 5.25" drive.

Are drive rails a standardised part that will work in all atx cases? Or, do I need to buy one specifically for my case model?
