I've seen a lot of jobs asking for "IMAC" and they don't seem to mean Apple iMac

Example:
Desktop Support Engineer - Windows - Mobile - Troubleshooting - London - Job: 65746024 - CWJobs.co.uk
If anyone could let me know what IMAC means in terms of desktop support jobs, i'd be grateful.
Thanks in advance.
EDIT: Seem to have found out after a bit more google-fu.
IMAC stands for (installations, moves and changes)
