I have a rather small desk, so if I were to set up a lamp, it would be pretty much right next to the iMac... I'm wondering, though, would I run the risk of damaging the iMac in any way by having a heat source so close to the computer? The lamp takes a 25 watt bulb, max... no higher than that. The space of my desk is comparable to the one shown in this picture: Except, I don't have a second monitor and the iMac is centred in the desk, nearer to the back, with a good little bit of distance between iMac and keyboard/trackpad. What do you guys think?
