Intel no longer makes desktop boards.
You can find information on processors here:
Once you find a processor you like, you can look up compatible boards here:
Intel RST, which implements RAID support, is provided in *all* Intel chipsets. The processor in use doesn't matter.
Remember that, before installing your O/S, you should go into BIOS Setup and change the Chipset SATA Mode from AHCI to RAID. Again, you should do this before installing your O/S.
Hope this helps,
