sean, I don't like systems that have the pre-set shelf grooves though, I have too many CD and DVD box sets that require alternate storage. That (and out of sight, out of mind and out of dust) was my biggest critical feature.
I am also mechanically challenged, so anything Ikea-like, and not already assembled, is a pain in the rear to me

I don't like Allen wrenches!
That stuff is skinnier than mine, but more than twice as tall, so it evens out. I have 3 cabinets 36" W x 60" H ( 3 at 20" each stacked) x 20" D which could hold 1000+ DVDs (I only have @ 200 DVDs, the rest is music and software CDs, tapes, ZIP disks, and some open areas for junk, magazines etc.)

p.s. why is it that forums like this elicit the need to share the most boring facts of your life! LOL
