So currently I have a flat desk a little like this: And I use this for my MacBook, however I've just ordered a 23" monitor and I'm planning it on using it for my MacBook and for my Xbox. I'm wanting my desk to have a monitor shelf on it so I can place my monitor on top of the shelf, and hide place my MacBook and my Xbox under the desk so I still have plenty of space and it doesn't look as messy! How is the best way of doing this? I don't want to buy a brand new desk as this one is fairly new, is there anything I could buy such as a monitor stand or would I be best trying to do DIY with a shelf and some small legs? Thanks!
