Hardware recommendations, not "enterprise" budget.

Soon I'll be purchasing a wireless N card for my current FreeBSD system 
since I'm not yet ready to add ethernet to my house.  What would be the 
current recommendations for using wireless N on FreeBSD?  My router is a 
Linksys E2000, which supports 2.4GHz and 5GHz but not concurrently. 
Supporting 5GHz is a strong preference but I doubt I'll have much luck 
getting everything else to work at 5GHz.

I'm also thinking of an HTPC.  For low power and mostly silent hardware, 
what's the best?
