Where to buy Omnia NAS?

Anybody know where to buy NAS extension for Omnia?
AFAIK, case is still available here Příslušenství Turris Omnia | EMKO Case a.s.
But where to buy SATA power cable? And mPCI-SATA controller?

I found this topic:

but can’t believe it is the only way how to make it (and DIY, of course).

https://www.discomp.cz/turris-omnia-nas-kit-for-models-rtrom01-xx-case-controller-cables-_d81320.html but “not in stock” so perhaps not.

The NAS kit is available on Discomp again :wink:
