I leave it on 24/7 because A)

I leave it on 24/7 because A) I don’t pay electricity and B) I’ve had awful experience in the past with Standby. But mainly it’s “A” 🙂

For your other point…I can live without system backups. I can easily share my folders myself. I’m using SyncToy in WHS anyways to backup my important data. And I use RDP whenever I need to login. Only thing I’ll miss is the File Sharing, but I can setup a Filezilla server quite easily. What else could I be missing?

And you’re right, if it’s just a WHS, then Core i3 is overkill…but i can justify that if i’m dual-purposing it in the bedroom 😉
