Advantages: Very versatile mid range server Disadvantages: support web site can be awkward to navigate
...and and 4 143GB 15K disks for the data configured as RAID5 (with the addition of an IBM7k RAID card) with a hot spare. This gives a 73GB OS partition which should be ample for most SBS installations including the exchange store. I tend to find that most SBS base builds come to about 20GB once everything is installed. This leaves just over 50GB for the exchange store and page file. The data partition would then be about 250GB which should be ample for most SMB's.

All of this is pumped through the new Hurricane memory processor and X3 architecture which basically means blistering throughput of data.
Further back and to the left and down as well if I remember rightly (it's quite big) are all of your expansion slots and where the RAID card plugs in. It is secured front and back by some nicely fitting clips that click reassuringly into place (don't forget to connect the battery).
At the back you will find the two hot swap power supplies with room for a third once you unclip the metal cover blocking the empty space where it should go.
As a nice final touch the the fault panel that is normally attached to the side of the X236 is housed...
