SSL Proxy with category based filtering

[Heli0s]

Can anyone recommend a good tutorial that shows how to setup pfSense with an SSL proxy (MITM) using Squid with a category list?

Also, what PC specs are needed to have a 100MBps connection with an IPS (Snort)?

I was thinking about getting something like this, but I'm not sure if it has enough horsepower: http://www.amazon.com/gp/product/B00MQLWZZY?colid=3A7DMUORM2LFP&coliid=I2IHP8BJP1YVEA&ref_=wl_it_dp_o_pC_nS_ttl
