I've already told you a bit about how the private infrastructure looks like. I use a Sophos UTM as my firewall, which has replaced my old Fritzbox. Michel has kindly put the hardware configuration for the UTM online on his blog:
I have the same hardware except for the SSD. My model of SSD is OCZ AGT3-25SAT3-60G (it was once on offer). Maybe one or the other can use it, I can only recommend it
