Here's my current setup. Needs a bit of improvement still.

A few years back I thought getting two big touchscreens would be amazing to use for making music. I rarely touch them. They get dusty all the time. They are too reflective. The border around them is way too thick. They are too big to be useful in this configuration. I'll be replacing them with normal screens and probably go for a vertical arrangement instead.

As you can see, there's a fair bit of stuff on my desk. There's a USB sound interface that could be rack mounted but I've been too lazy to buy or make anything to house it. I have a pair of headphones, a wireless headset and a Rift hanging off of the microphone stand. I rarely use the microphone and guitar at the moment (considered trying some voice acting, not particularly good at guitar!)

The desk was originally 2 desks from an Internet cafe that was being refurbished. I cut the ends off them and joined them together to make a desk to fit the space I had and stuck some metal legs onto it (used to have a big ugly brown metal frame). Oh and made some holes to add cable grommets and it has an IKEA cable tray underneath.

There's also a slide out music keyboard underneath (made from some bits of wood and a drawer runner, it's quite clunky and I'm tempted to use some rack rails instead).

The drawers were to store stuff from my desk in but I just replaced that stuff with other stuff...
