Just removed all the old pc's from one room, ready to install new ones on Monday, cable-tieing, joining to domain etc, probably be all over by Tuesday afternoon, giving me the rest of the week to re-image the other room in this block.
The other tech's got the week off on holiday, so I'll be able to crank up the music and crack on - looking forward to it.
I've sent a whole staff e-mail out telling them that the rooms will be unavailable for revision classes and catch-up. I did that when I replaced a room full of pc's this time last year, but I still had a teacher come in and try to use the room. 'Can't we use the ones you haven't taken away yet?'
