Your friend Bob is looking at a considerable investment of both blood and treasure. The best advice you can give him is this:

1. Buy a book and read it.

2. Teach him or her to use the search function - hint the built in search on most sites is less than optimal so consider using Google to search your favorite site.

3. Point out that a wealth of information is available on this and other forums. Suggest that he/she start by reading the stickies and tutorials. See my signature line for a good example that applies directly to your situation!

Really. I don't mean to be rude. Here is the best advice I can offer. Do your homework and come back with a post that provides a detailed outline of the setup you are considering. Then ask for pointers, input, and advice. You will get a lot of support if you approach the problem from that angle.
