I think that the future of computer customization is in virtualization. Instead of having a single very expensive machine to upgrade, we just go grab 30 servers from a bulk seller and use something like Xen or Proxmox to use them all as a single machine with 1 virtual CPU, 1 virtual disk and 1 virtual network interface. Got another computer? Just add it to the pool. So while computers are getting harder to disassemble, it's also getting easier to pool them together to share compute, network and storage.
