If your computer has a USB port (and can boot from USB), you can use my USB installer to do a vanilla or kickstart install SL6.5:

(download tarball is two levels up).

If you have infrastructure for network booting (dhcp+tftp+pxelinux), it is trivial
to network-boot the SL6 installer and install over the network. (I find the speed of
USB install and network install to be about the same).

I personally recommend a reinstall to: a) avoid creating a mongrel system maybe hard to maintain long term,
b) removes all doubt about "who knows what was running on the computer before you got it" and
generally gives you a clean slate to work with.
