It really depends on what the server is being dedicated to. Xen and any other virtualization comes out of your overhead costs, unless you have a specific need for it (like being able to migrate seamlessly to EC2) don't bother. For what you are planning to do Ubuntu server edition would probably cover most of your needs and give you enough support to quickly resolve problems. Don't bother with softraid, if your data isn't important enough for you to afford a dedicated RAID controller and the disks to go with it; you can live with the possibility of losing everything up to the last backup (you will be taking backups).

I disagree on the soft RAID vs. hardware RAID (if by soft RAID, you mean the md layer in Linux). I'm not a fan of hardware RAID, in general. I wrote the following ages ago on Slashdot in response to the same kind of disparaging statement about soft RAID: The data integrity benefits are still present, as are some performance benefits in some circumstances (in fact, Linux RAID is demonstrably faster in some workloads than a top end Adaptec hardware RAID controller, though this is the exception rather than the rule) That said, I hate pretty much all RAID controllers (whether software or hardware). Linux software RAID means that I can drop the disks into any PC and access the data. Every RAID controller from Promise, Adaptec, and Tektronic requires me to use their disk format, and if I lose the controller I lose the data until I can get another controller. Sure, in high availability environments, you keep a spare...but with Linux software RAID, every PC in the office is a spare controller. That's my kinda redundancy. I've even had two identical Adaptecs with different firmware lead to pretty massive data loss during a server migration. Thankfully there were good backups. I've never had similar problems moving Linux software RAID disks into a new Linux box.
