Can't fit internal HD

[jroot00]

I have this case:
https://www.cclonline.com/product/259614/CIT-RAIDER-RGB/Cases/CiT-Raider-ATX-Mid-Tower-Gaming-Case-Black-with-4-x-Halo-Spectrum-RGB-Fans-Aura-Sync-Support/CAS3451/

that I cannot workout how to fit this drive into:

The HD is too small to slot into the bay at the bottom front of the case here: https://flic.kr/p/27ZxZEd

Am I missing a bracket?
Thanks

Unless ofc you're referring to a 2.5" form factor HDD, in which case your supposed to put it on the motherboard tray's extension to the right of this image

thanks Luftij, the drive was bought around 2008, here's a photo of it: https://flic.kr/p/NBUqbm.

For your last point- do you mean just screwed into the bottom (floor) of the main motherboard section?
