Windows 7 has perfectly functional power settings and as you've only got 6 machines it'll only take you a minute to go around them all and make sure they're set to sleep after say 15 minutes of inactivity? Personally, I'm a bit of a tree-hugging hippy so would prefer not to waste perfectly good power - in the absence of any formal plan from management I usually like to have one put in place anywhere I work: employees to please turn their computer(s) off when they leave for the day. Modify power saving settings to prefer sleep after 15 as a backup in case anyone forgets (monitors sleep and lock after 5-15 minutes, depending on user preference). I do however always have a point of presence inside the firewall, usually via VPN/SSH, and like to have wakeonlan fully setup so I can get in remotely and fire up systems out of hours for planned maintenance or emergencies. As for the economics of the wear and tear of daily powerups vs the electricity bill of constant uptime, I'd really need some concrete figures from some tests before forming an opinion - think you'd need some stats at major scale though for any kind of reliable conclusion. I think I'd be moderately surprised if the constant electricity bill didn't turn out to be more expensive long term than any aggregate wear and tear cost from daily reboots. I'm not even sure how a study could reliably measure such things without accounting for all the random confounding variables though...
