Need Hard Drive Sleds

[Austone]

Hi guys, I have recently embarked on a new adventure building a NAS. I picked up a new to me DIY PC case and lo and behold it does not come with any hard drive sleds. Any ideas on where I can get my hands on some sleds compatible with this case? I emailed DIYPCUSA and they have not responded, it has been over two weeks.

Since I doubt that is a case that accessories are just sold for, it maybe easier to just replace that hard drive cage.  They make universal cages, see this random example . Though you wouldn't need to use the fan part of it.
