Where to buy wood in the UK to build arcade stick case


I’m interested in building an arcade stick case, and was wondering if anybody could recommend a good place in the UK (Edinburgh, Scotland to be precise) to buy wood from. Also any extra information on how you go about picking what wood and how much to buy would be great too, thanks! (I quite like the darker wood cases I see, but whatever wood is easier to work with would probably be best for me)
