You can customize the partitioning scheme during install. In your case
I would do the following. Let Anaconda setup the default partition/LVM
layout but check the box to allow you to customize it. Then leave the
whole volume group partition but adjust the logical volume down to
40-50GB of whatever you want. If you start to run out of space later
you can add extents to it. I'm not sure what backup method you're
using but you may have to change it to backing up the logical volume
instead of imaging the physical volume if that's what your doing.
