What are you doing for home NAS?

[Mark Komarinski]

I have a bit of end-of-the-year money that I'd like to spend and 
thinking of a dedicated NAS device for my home rather than having hard 
drives start spilling out of my basement server.  I figure I need about 
4TB usable, so either 2x4TB or 4x2 or 3TB is a configuration I could 
work with.

In looking at the products that are out there for standalone NAS, 
they're REALLY expensive even before adding the cost of drives.  The 
two-drive systems seem to be just barely adequate for my needs, and the 
four-bay ones jack the price up to just going BYO ($700-$800 without 
drives).  Even then, the Drobo a friend has puts its NFS server in 
userspace (WTF?) so performance and features like file locking are lacking.

So I ask the question - what are you doing at home?  Build my own? Have 
any device that's still for sale you can recommend?  Anyone using 
FreeNAS and have suggestions?
