While that is technically true as well, a backup solution would be vastly superior to either option, and more then likely cheaper as well. I'm not trying to start an argument or anything but the OP said his primary concern is losing data. Neither a server nor a raid array (or both) really help in that regard. A server with a raid array protects against exactly *one* potential source of data loss, a hard drive failure, and doesn't even do that completely (it is not unheard of for multiple drives in an array to fail at the same time) and of course introduces it's own problems, i.e. the array itself can now fail, if 3 years from now the MB dies the array dies with it and now he can't purchase a replacement, etc. . A properly implemented backup solution protects against all types of data loss, and is almost certainly cheaper.
Obviously if he wants to build a server too that's all well and good. And if he is concerned about being without his files for more then a day or two while he waits for a replacement drive in the event one fails, maybe even a raid array. As long as he is aware that after spending all that money on multiple drives for the array, and the server, and what not, he hasn't actually addressed his primary goal of protecting his data.

Were I the OP, I would probably build a server anyway just because I find them extremely useful in their own right, but that is a separate issue. For protecting my data, I would skip the raid entirely as I am not running any sort of mission critical applications that require 24/7 uptime, and just implement a proper backup solution.

Theoretically it's enough. But I'd still use an alternative RAID method instead of RAID5 with disks above 1TB. The chances of having a read error while doing a RAID5 rebuild with disks above 1TB is so large that you risk loosing your entire array even with a single drive failure.
