zalasur, All the hardware has arrived. The first step will be the hardest; getting Arch Linux onto the compute module. But the real nailbiter will be if I can get the PCIe SATA card seen by the kernel after I boot it up. Once that's done I just have to set up the RAID 10 array and get the volume exported via NFS and SMB. From there I can make it visible to the other devices on the network.
Easy peasy one two threesey.
