Looking for a mini PC capable of running pfsense + VPN /ipsec

[ddarlington36]

Looking for a mini PC capable of running pfsense as a standalone device on a home network with VPN, IPSEC OPENVPN squidguard snort VoIP this is for a home network. Total clients 8, connection 100m/50
The VPN will mainly focus on 2 clients of the network.
Most of the clients are streaming clients Smart TV's or host machines for gaming /surfing /video and a freenas hosting all the media to the target machines

My focus is to move away from a virtual client as the  gateway/router and shift the workload to a low TDP device I've been considering this for awhile I just hope the device I've been considering will be adequate.
Budget trying to keep it around $300-350. Size is also a consideration small if possible
http://tinyurl.com/zvdrutf  i5 4200u 4/8gb  either 64gb/120gb ssd
my focus here was AES-ni plus the Intel NICs 82574l  there is also a i7 4500u variant but its only a dual core

My other options are just go all out and build a mini-itx either jetway nf9j-q87/i3-4170 , or go with an Intel atom platform D2550 will that be enough on the cpu?

There are many ways to walk down the road for you here.

Fits exactly the needs in my eyes:
pfSense store SG-2440 would be nice matching to that case and is supporting the pfSense project.
Look at the pfSense or Netgate store.

Is a good, silent, and small alternative to that:
PC Engines APU2C4 is also running well for that use case for sure.
As a bundle for ~250 €

No AES-NI but powerful enough to handle all:
Jetway NF9HG-2930 ~$199
2 x 4 GB ~$40
mSATA ~60
M350 ~$40
PSU ~$10

Push all other away and is really upgradeable and powerful or strong!
Pending on the chosen CPU a real pfSense bomb
ASUS Q87T / Gigabyte Q87TN
CPU as you need it
