Dedicated RAID 1 PC for storage?

[Snikerdoodlz]

I have some personal data to back up (files, photos) that I currently put on external hard drives. I have 1 1TB USB hard drive and a 2TB internal 3.5" drive with an enclosure. I love building PCs, but I can't build one that I'll use since I have to use a laptop for school. Is it a good/bad idea to build a dedicated PC to use to back up my data using RAID 1?

You can buy external enclosures if you don't need any fancy features. Some two-bay ones also can do RAID1 but I don't know how well they work.

You can either build or re-use and old PC, or get a NAS enclosure, You can get like a DS218j or a DS216se for pretty cheap.  Add your two disk's configure RAID 1 or SHR-1 (same thing basically) and setup the network share
