When it comes to filing at home, we think Bisley filing cabinets are perfectly suitable. You can buy them extra small if that's all you need or go big if you have more filing needs at home. We personally love the ones with the shallow drawers.
They come in lots of colors that are sure to match your decor (and a stripped-down metal finish). Plus, they're available retail at The Container Store, so it's super easy to get your hands on them.
We know someone who bought a bunch of the shallow-drawered ones in the metal finish and used them as pedestals for "hollow wood door" desktops along an entire wall of their apartment. It at once gave them tons of storage space and worktop space. Unfortunately, they've since moved so we can't provide pics, but hopefully you get the idea...
