Adding hard drives to Z2 G9 SFF

[adehnert]

I bought an HP Z2 G9 SFF without any hard drives, and am now trying to add a couple. From Quick Specs, I think I should be able to fit 3 3.5" hard drives:

> (1) Shared internal/external 3.5" bay
> NOTE: This shared bay is supported only with Core i7 / i9 processors.
> (1) Internal 3.5" bay
> (1) Internal 3.5" bay (optional in Standard SFF. Not Available with Full Height Graphics Base Unit)

(I have an i7 processor and I think the half-height graphics base unit.)

One of the bays seems straightforwardly usable, but the other two looks like there's probably some carriers that are needed to do this? Anybody know if the carriers are something I can acquire now?

Having poked a bit more, I noticed four seemingly-unused screws next a label saying "3.5" bay". Screwing them into my hard drive they worked as ~rails to slide the drive into the internal/external bay. (To get my drive in far enough, I needed to twist out the metal piece at the end, but could leave the plastic slot in the front panel in place. With the metal twist-out gone, the drive clicked into place.)

I suspect the other internal bay does require an additional drive cage component, and would still be interested in a source or part number if anybody knows it.
