Hi and welcome. I'm really new here, too. The system on your link is similar to one Ikea has called "Trofast" that I was thinking of getting for craft supplies. They design is similar, they also have the option of drawers and different size bins. Here's a link:

Here is a link that might be useful: Ikea Trofast System

I haven't invested yet in anything to organize the toys other than the pop-up laundry type basket from Ikea and a soft toy chest. One thing I have to say especially with my youngest (18 months), her big joy is taking things out of the toy chest etc. sometimes more so than playing with the toy. At some point we have to get more organized with the toys but right now it is the adult clutter that is more the problem. Theoretically they (my other dd is almost 3) have a space for all their toys ... it's just about making sure we have cleaning up as part of the bedtime routine which I must admit I have been somewhat slack about.

Astrid, I bought the same item that is in your link for my gdd. It seemed like a really good idea at the time but even when it was perfectly organized, it still looked messy. I realized that it was because there were no lids. Eventually, my dd got rid of this system because of this fact. I'd say go with any system that you can close up each container. It will definitely give you a sense of being clutter-free.
