Do HDD Brackets come with a PCIE SSD Only Late 2013 iMac?

Hi.

I'm wanting to get the 1TB PCIE SSD option, BUT also put in my own 2 or 3TB mechanical drive in at a later stage (as well as the pcie ssd). My only concern is that i'm not sure if the iMac will come with the necessary brackets and fixings inside for me to mount and install my own drive at a later date.

• The bracket in question

Anyone have any insight into this?

Does anyone have a PCIE ONLY iMac to validate wether or not the HDD brackets are there even with the absence of the drive?

Any help would be very usefull!

Thanks.
