Oooo, that's a tough call. I have a lot of things on my desk that I like! There's my PC which cost me a lot but I built it myself; my Toothless plush that a good friend got me from Universal in Florida; loads of stress toys and fidget things... but if I really really had to pick one, I'd say my keyboard. I hand built the switches in this which took me days and it's perfect for me now :3
