white gaming pc £1000

hi, so someone helped me out with my build, and thought i would add a little colour theme to it, just want to ask how white-er can i get this? without going over the budget, also if someone could recommend a better looking white micro atx case, as im really not sure with the one that i picked. also im planning to buy a monitor, just want to ask if the one in the build is good enough for my build
