I had a WHS, and the only complaint I have about it is that redundancy is accomplished via duplication. Depending on how much data you have, that can greatly increase your total cost of ownership. To achieve 10TB of redundant storage on WHS, you need 10x2TB disks. To accomplish that with unraid you need 6x2TB. The downside is that unraid will only protected you against a single disk failure, whereas WHS might protect you against multiple disk failures - depending on which disks go.
