Instructions and a downloadable program from Microsoft to check the checksums is available through Microsoft Knowledge Base article 841290.

Freeing up disk space now, more than ever, involves removing the installation files for GUI modes, Server Roles and Server Features.
Since that time, many improvements have been made to the manageability of Server Core installations.
