I currently use macs and I was looking at the MacPro, but I don't like the graphic card options.

I don't like Windows due to past experiences.

I have used unix before and get on ok with it.(probably why I like Mac OSX)

So with the above points in mind I have decided to build a Linux box.

But I have to get it right first time, so I would like to put it to the members of the forum to put your suggestions forward.

The areas I would like your views on are the following:

CPU, AMD/Intel, dual or single processor, single core or multicore?
Motherboards, features, chipsets etc
Hard drives, SATA or SAS
Graphic Cards, ATi or nVidia, pro level or consumer level etc

Any & all views, opinions, comments will be very gratefully received.

Cheers

Chris
