He uses the suggested power supply, the one that Tower lists on that page. What LHS has the 110? Hobby Town is the only one I can think of, unless Hobby People got one recently and have been hiding it on the bird nerd side. I just checked HP's site, if they have one, it's not listed on there. Also checked Hobby Town's site, but I can never find any crap on there anyway......Hot Rod's maybe? :D
