If you are fortunate enough to come by a SERVER UNIT, then all you have to do is wipe the hard drive(s), Format it/them and install your operating system onto the primary hard drive. Check the BIOS to determine this, make sure you have enough space...at least 10 Gigabytes, which a SERVER should easily have...and set the primary drive to boot up first...easy.

Also be sure and periodically run scandisk and defragmenter on your system to keep it in top shape.
