I've always kind of wanted it too lol, but I wouldn't have a use for the lighter. There's a lot of stupid knick-knacks like that I wouldn't mind having for my PC.
There's this USB powered drink cooler (USB peltier essentially). I actually read a review on it, and it works if you put your drink in a cup with a flat bottom, but it doesn't work for pop cans because they don't have enough surface area on the bottom to make good thermal contact.
There's also this storage drawer from Thermaltake, except I'd have to ghost it so my front panel would still look clean. Problem with this is then how do I open it? So I thought maybe I could rig up a motor to open it. Then I just nixxed the idea, because it'd be too much time spent on something that wouldn't really be that useful anway lol.
