This cabinet has pre-drilled holes all along the side so you can adjust the space between shelves. Unfortunately they're not the entire length of the cabinet, so there are limitations but you still have quite a bit of adjustability room. Ikea stocks the pegs for these holes, normally you can get them for free or a small fee. (like $1 for 8)
It don't get much easier than that.  |
Cool, thanks for the info (strange that they don't stock the glass shelves then, too -- you can buy extras for the Billy System, for example, for like $9).
