Might be nice to get close-ups of the PCH and hard drive, in light of the Sandy Bridge bug. Initial reports are that the HD is connected to an SATA-III port and should therefore be unaffected... but it would be nice to know the exact HD model regardless for those considering upgrading it.
Unfortunately, preliminary reports indicate that the optical drive is connected to an SATA-II port, which may be affected by the Sandy Bridge bug, so I would hold off until the situation is clearer.
