The SATA II spec supports hot-plugging and recent kernels are 
implementing it for more and more common chipsets (e.g. 2.6.24 
introduces support for the
NVidia nForce 5 SATA controllers I have). Check out the status for 
individual chipsets here: http://linux-ata.org/software-status.html

If you spend ~ $20/drive for hot-swap capable bays (I personally use 
http://www.newegg.com/Product/Product.aspx?Item=N82E16817994027, but 
there are many out there) you have an almost professional setup for the 
enthusiast home user.

I'm using it for ~ 15mo and it works fine for me.
