if you want raid 5, why not just stick a raid card in?
You'd have to spend half again on what I paid for the server for a decent RAID card with enough ports that does RAID 5, it's not really worth the effort when software RAID is just as good (the only drawback being needing the OS installed to keep it alive). I might fit one for expansion later on though once I've got to grips with it, I've not even had a chance to take it out of the box yet
Also it seems these make for great media servers/HTPCs and its something I would consider in the future, all I want it for is decent redundant storage. For someone not interested in RAID or that just wants JBOD you have a small, quiet unit with enough grunt and low power consumption providing you fit a HD decoding graphics card, plenty of success stories on HUKD as XEntity mentions.
