These tiny pcs are great on paper but absolutely terrible in practice. They run HOT, dangerously so for the longevity of your purchase. Even with low wattage processors these will bake in their own waste heat without external cooling. Lenovo absolutely dropped the ball as the few I have only have a single heat pipe and that is IT. Invest in a usb fan to blow through the grill at minimal if you do purchase and steer clear of 7200rpm drives as they will be deep fried in no time. If you can cool these little boxes properly then you can expect to get a long happy life out of 'em.
