This is wise, but 240v is quite nice for computer equipment. I had an 
electrician run a 240v 30a (10g wire) circuit out to my work shed, where 
a subpanel is installed with 120v 15a and 240v 15a circuits for the 

240 just allows you to get twice the power to the device using the same 
size wire (14g for 15a for example). But modern switching computer 
supplies are more efficient at 240v than 120v so you waste less power.

120 is good for like light bulbs and stuff. Drawing over say 10a 
continuous at 120 will pretty much burn up sockets and such in short order.
