Will this prebuilt device suit a new home build?

Hi All,

I've been looking for a low power but capable system to protect a bunch of devices, 2 ipads, 2 phones, 1 DMZ (OMV NAS), 2 computers, and soon IP cameras.

Current internet is 36Mbps down/1.5Mbps up, but would build and scope a box for expansion and upgrade. I would look to turn all features on inc IPS/IDS.

Being based in Australia, we are a little limited on the hardware, and I came across this box and wondered whether it would suit OK, comes in around $450 AUD.

Notably, I understand to avoid Realtek and only use Intel NIC which this box has. Also box is scoped with an i3 haswell (4010U) and we can upgrade to a 128GB SSD. Its CPU passmark is around 2441.
