Tip on replacement hard drives: you can use a SCA drive with an adapter inside some Sun boxes, or my personal favorite, a Sun "UniDisk" enclosure with a SCA drive inside. SCA drives are really cheap, even for big ones (they go up to 300 GB), and you can still get some of the later production drives with 0 hours on them. You'll usually need to create a partition less than 1 GB within the first 1 GB of the drive, or your Sun won't be able to boot it. Larger partitions after that are OK.
