Get rid of the dust!
It's not good for cooling, and lack of cooling is a performance and hardware killer.
Don't use standard vacuums, they create deadly static. Best if the tower is moved to where compressed air can be used to blow the dust out. Wiping of the fan blades with a soft cloth, and use of a soft, long haired brush can aid in removing stubborn dust.
I am not suggesting that you do the take apart, but this article has some good pictures of how much dust can accumulate where you can't see. This is where compressed air can really help.
Take care, and be gentle.
As for the hard drive, preventive mainntenance of repairing the hard drive directory with Disk Utility, or, better, Disk Warrior, is essential to keeping performance up.
Defragmenting utilities, IMHO, should not be used. OS X takes care of minor defragmenting.
Cloning a system to another hard drive, using SuperDuper! , is actually a very good way to get defragmenting taken care of, and keep your system backed up.
Time Machine makes backups. These backups are not bootable. The data is good for restore, but the mechanism is not the same as cloning.
Cloning copies all files, OS (hidden files too), applications, data, etc., to a chosen drive. In the process, a file that may have been spread accross a couple of sectors, is written to the clone volume in a single, unfragmented manor.
This article explains.
The other benefit of the clone volume, unlike a TM volume, is it is not only cleaned up, but also bootable.
So, the cloned volume, can then be used as a system drive. When backup is neccesary, clone the clone back to the other drive. Again, files are all cleaned up, and you always have two complete, bootable systems, with two complate sets of applications and data.
