Give yourself a solid 3 hours to build it, and even then expect things to go awry (a missed screw here, an unaligned pilot hole there).  Most importantly, build it on a soft surface like a rug.  When I finally flipped the desk over on completing it, I dented the rather delicate particle board desktop surface in a corner (luckily fairly unobtrusive).  Overall, though, nice looking desk.  My daughter is very happy with it.  One constructive criticism - please add sliders or small protective base legs to keep floors from scratching and to facilitate moving the desk.
