Use Existing Data Drives In New Whs Server?

Hi There,

Im currently running an Aspire easyStore H340 with 4 1TB drives. It's recently started developing hardware problems, which I think might be down to a goosed motherboard.

I'm considering building my own WHS, and am hoping to use the existing drives in the new build. I don't currently have anywhere to store the files currently on the drives, if I did a fresh install of WHS for the new machine, would I be able to 'recover' or access the existing files on the new server?

Any help would be much appreciated,

Cheers,
