Well discussed, and if you google something similar to your subject, you'll find plenty of hits on installing XP to a unit with a SATA drive. Adapting it for RAID shouldn't be overly difficult after you clear the initial hurdle. Think of it as a test. If you can't figure out how to install XP on a SATA RAID setup, how do you ever hope to be able to troubleshoot any problems that may come up later?
Of course your next problem will be finding drivers for the rest of the hardware that work with XP. If you bought a unit that didn't have XP as an option for install at the factory, then there's a very good chance that you're setting yourself up for a lot of wasted time and effort.
Plus XP is officially over 10 years old now, and it's already on life support. All support for it is set to end within the next year or two. So why not go with Windows 7 as the main OS, and then just install XP into a VM if you absolutely must have it for some reason. And if that's the case, then you should probably be taking a good long hard look at the reasons that brought you to depending on a specific OS revision like that. No OS revision is supported indefinitely, and very few will ever enjoy the kind of long life that XP more or less lucked into. XP will quite probably be the last OS with over a decade of active use.
