making a juke is pretty easy mate , are you handy at woodwork ,
if not you can always get a carpenter to rip something up
use mdf
now how much is your budget , computer (good if you have one) , touchscreen , amp and preamp , or run active speakers
as i said i just built a corner unit that my computer sits behind still looks and acts like a juke
my cousin just mounted a touchscreen flush with his wall which looks really modern , he just used a mounting bracket that swings out when needed and run all hes leads through the wall to a computer that is hidden behind his bar
plenty of ideas here on building
you can do it very cheap or like i did , i bought quality amps speakers and used an old cheap tower computer , good touchscreen so all up probably around 3k for mine but the speakers and amps were 2200 , screen was 500 , so if you have all that you can get away with a couple of hundred
heres my build it might give you ideas -
