I've just ordered £400 of new stuff, namely an MSI K8N Neo4-F and an MSI 7900GTX (I must have a thing for MSI at the moment

). The thing is, I've got a Raid0 running at the moment, and I've just got XP exactly how I like it, so I'd quite like to preserve it.
Will it just be a case of enabling the Raid on the SATA slots, and automatic detection doing the rest? Also, are the NF3 and NF4 similar enough to not need a repair install of XP?
