Kevin,
  It is impossible to tell if your configuration will perform well or not without knowing the load that your application will place on it. With 5 of the 4.3GB drives (7200 RPM?) running RAID5 you can handle approximately 350 reads per second or 87 writes per second or a combination of the two. Depending on the memory in your system and the workload this may be sufficient. If the load is too high, you may be starting out with an I/O bottleneck.   Another issue is the fact that you are forced to share your data and log files on the same volume with the OS. Again, if you are running a very small system with very little load and no update activity this will be fine.   Good luck.
