Built new hardware, need software/ package suggestions

Hi all,

i just built a new custom router / firewall device

 ASRock AM1H-ITX 
 AMD athlon 5350

i currently have it running pfsense on its own i'm wondering if anybody has suggestion for better software to run on this and/or packages to run in a home environment.

i was considering running pfsense and something else like free NAS in virtual machines but i dont know that will create security issues or not, ill need to do a bit more research on that i guess.

also there are young kids in my house i would like to implement a content filter but most of what i've tried with pfsense doesn't work well enough to actually filter content while being obtrusive and slow(i can go to tits.com, but i cant search for hunting bows? WTF) or is just a black-list i could download and apply myself.

thanks
