Shuttle XPC SN25P
 

To demonstrate the size changes of the Shuttle Athlon SFF lineup over the years we stacked 4 of them from oldest on the top to the latest on the bottom. We start with the SN41G2, then the SN85G4, then the SN95G5, and lastly the SN25P. As you can see the last two Shuttles have a significant jump in size with the SN25P sharing the chassis of the SB95P v2 which had to have enough space to cool the hot P4s. The Athlon 64 does not require this level of cooling, and the previous size chassis would have been fine.
