For my two cents I would have to disagree with the Xeon approach. A cluster of Xserves is probley going to give you more speed and storage for the buck than a Xeon machine. We have a small cluster of Xserves running osX server and we find that it is very fast, and the new g5 slusters are even faster. Another alternative that has been done in the past is to actually run Linux on Xserves. I don't know the details of this but I do know that this has been done. If you look at the bioteam software as well there are over 200 bioinformatics tools included with the package and they all have a gui interface which is very nice for the average user. As far as management features you can't beat osx server. Everything is so easy to do you don't need a bunch of IT people to do it for you. I am a microbiologist and I admin our cluster. I think the "most tools for bioinformatics under linux" is not exactly true. I don't think you will find much trouble finding an osx port for most of the tools. FYI there is going to be a webcast about the Xserve cluster for use in bioinformatics next thursday, you might want to watch, you might get some of your questions answered. http://education.apple.com/webcast/workgroupcluster/ Mike Michael D.
