All scripted.  Backups, overnight checks, alerts, DBAUtilities database, tools (sp_blitzX, sp_WhoIsActive), monitoring jobs, MaxDOP and other non-standard settings, backup locations.  There are some minor hand tweaks - IFI, TempDB and Model growths and sizes and startup trace flags, adding to Server Group for SSMS - but pretty much everything is standardized, predictable and reliable - as well as being quick and easy.
