I have not done a project like that . When I price out a NAS project it is actually less expensive (when you think of equipment and time) to get one premade. The NAS' we use are WD's right now. The boss also does not like to have the TB size of the NAS' too large, I limit the size to around 8TB to 12TB.
If you do make a NAS with NAS4Free, I have looked into it, remember it is a software RAID not a Hardware RAID. What do I mean by that? Software RAID's are basically made using a Volume Manager (usually Linux VLM or VLM2), hardware RAID's are actually considered a 1 physical disk to the PC when managing the Volume(s) at the operating system level. I myself prefer hardware RAID setups. This is due to the ease of replacing disks if needed. Also, Hardware RAID's are a bit easier to recover when things go bad.
