1. Secure for both data desaster and network attack
2. Easy for using
3. Easy for maintenance

To cut down cost, I use only one RAID-1 on PDC (Primary Domain Controller), and backup most important data (source code, project documents, etc.) to Lin (Linux Development Server) everyday.

I found attacks from Internet is less than Intranet. Thus, security inside is more important. Firewall supplied by ADSL-Router is enough, I think. Other security policies will be supplied by OS and software deployment.

I'll record most details of deployment in my blog recently.
