IBM PS-2E ~5×-efficiency desktop PC (~1992) ◊ First serious effort at an energy-efficient desktop computer ◊ Early pizza-box, LCD, PC-card-based ◊ Superefficient power supply (even at part load), small, high power quality Cost more…but offset by avoided fan Marketers liked the silence (ergonomics) Absence of dust-depositing airpath reduced chip heating and warranty costs Small case, lockable in desk drawer (secure, almost no deskspace)
Simple RMI server substitution ◊ Several years ago, RMI replaced three (could have replaced four) Windows NT servers with one small NetWinder Linux box (now model 3100) ◊ Nominal power 14 W, no fan ◊ Faster and more capable than NTs ◊ Hardware plus software cost less than NT license fee on replaced NT boxes ◊ 98–99% energy saving ◊ Big space saving
