Looking for HDD 2x2.5->3.5 caddy

[kbelyhk]

So here is the story. I currently able to pickup a bunch of old SAS drives (SFF\2.5" 600gb 7.2k sas6) for absurdly low price (like US$10 a pop) and i'm looking to build home server for storing backups etc. I kinda like Fractal's Node 304, but HDD trays there is designed for 3.5" HDD and uses bottom holes of disk to mount, but idea of having 12 SFF HDD in such small case tickle my imagination.

 

So now i'm in a hunt of adapter\caddy which:

a) Can accept two 2.5" drives

b) Has ability to install on tray using bottom-positioned holes of caddy like on 3.5" HDD

 

Using my google how-to i'm unable to find anything suitable for my purpose.
