The folder grows quickly on Server 2008 and 2008R2, here is how to cleanup the old isntaller files.

On 2008 non R2 servers navigate to c:\windows\system32 and run vsp1cln.exe for sp1 cleanup, on SP2 run compcln.exe from the same location.

To clean up a 2008 R2 box do this:
DISM.exe /online /Cleanup-Image /spsuperseded this can also be used on Windows 7 with SP1.
