Parts to repurpose HP t610 thin client into internet router

While building a new (pfSense) home router, needed some parts to re-purpose an HP t610 plus thin client.

** Namely: **

* A drive caddy (impossible to locate).
* External WiFi antenna mount.
* Some feet to allow proper case ventilation for 24/7 operation.

Wanted to minimize hacking the original case so this is what I came up with.
