It occurs to me that I could probably seriously improve the performance of my 
computer by upgrading the harddrive.  It currently has the stock 320GB 3.5" 
Sata, with all of the data on a motley collection of external drives (USB 2.0, and 
both types of firewire).  Also, the internal optical disk has been getting flakier 
and flakier.

The biggest initial upgrade would probably be to replace the main drive with a 
SSD.  This would tremendously speed up access to the lightroom catalogs, which 
I do keep on the main drive.  The biggest SSD I found easily was 512, but apple 
lists 768GB.  Another possibility would be to pull the optical drive, replace 
it with an external USB optical drive, and drop a big spinny drive in there, so 
I'd have my current working raw files close to my machine, and not over a slow 
USB2 connection.

there are bigger SSDs, but the price/GB is worse, and you reach the point where replacing your computer might be the better value:

you have a 3gbps SATA bus, which means you won't get the most out of a fast SSD, but you will probably beat Firewire 800; because of your slower bus, i'd consider a less expensive SSD model, such as the Samsung 840 Series, for which there've been a number of deals lately (best i've seen was $300 for 500GB)

you could also consider a modestly sized SSD in the optical slot, and replace the hard drive with something large, fast & reliable
