Hi, I'm planning to build a server to do the following

• Act as a file server (videos, pictures music)
• Run Squeezebox server
• Run Zune Software to allow wireless syncing to Windows Phone 7

I'd also like to aim for

• Low power usage (i'd settle for less than the 90-100Watts I'm using atm
• Flexibility, I might want to add a web server or sharepoint or...
• Something I can learn/test on, work is mainly a Windows shop but I do have Linux experience too
• I'd like to take a look at App-V (application virtualization) too
• I'd like it to cost less than $1000
• Quiet would be nice but not essential (it'll be in the basement)

I'm thinking of getting a technet subscription to get access to Windows Server 2008 R2 at a reasonable price ($199) So my plan was this

• Get a bunch of 2TB Caviar green drives to RAID up (RAID 1 or 6 probably)
• Get a Quad core CPU (Intel i5/i7 probably)
• Install a Hypervisor
• Install w2k8 R2 Storage Server for a NAS
• Install Windows 7 Pro to run Zune/Squeeze box
• Install any other machines I want to play with

Questions

• Can anyone see any issues with this or have any better ideas?
• Do you think I'd need an i7 over an i5?
• Is 4 cores enough/too much?
• Can anyone sugest a nice, reasonably priced case that will hold 6-8 drives and stay cool
• Should I wait for Sandy Bridge parts?
