Corsair 900D HDD Cage Plinths

Hi,



Does anyone know if you can buy the HDD cage plinths that are in the bottom of the 900D?



I am currently build a bespoke Apple Mac G5 NAS System that utilises two G5 cases that have been joined. It houses 6x 900D HDD cages (18 hard drives).



I need two, either new or secondhand and I am based in the UK.



Thanks.
