Suggestions for external enclosure for Raid?

[MrGuvernment]

i am in the market for an external enclosure for at least 4 drives, i wish to do a raid 5 / or raid 6 set up for keeping all my photography, and other important stuff on..


one that can do the raid it's self would be nice, but even if it was external and used eSATA to connect i could get a PCIe raid card ( 4 port) to do the raid.. i prefer one that doesnt have included harddrives, i will get them seperate


i want external as i am trying to trim down the room used in my case for the case mod i am doing..


i can only order from 2 places really, directron.com (http://www.directron.com/raidstorage.html / http://www.directron.com/35sataence.html ) and dell.com (or ebay)

so my choices may be somewhat limited, but i will take suggestions of others as sometimes Directron will order things in for me if they can

One i did like, but cant find any reveiws on is
