Rebuilding My Linux Box

I am contemplating the task of rebuilding my Linux box at home, it’s currently running Mandrake 10.1 and has 3 Hard Disks (2x18GB+1x160GB) and a DVDRW Drive…

Here’s What I’m thinking of:

• Replace 18GB Hard Disks with Larger ones (200GB?)
• Ubuntu – I really like the slogan “Linux for Humans“…
• Implement Software RAID (Mirroring RAID1 or RAID5)
• A New Partitioning Scheme (I wish we had Native zfs or Linux)
• A New Backup Strategy using rsnapshot
