@Kyber417 That's a really great drawer! Where did you find it?
Also @Legomaniaczone If you have smaller sets or minifigures you display and like to switch out often, you could also use spin tables/ Lazy Susans for rotation of your parts.
I'd determine which sets you want to display most and which you can have stored. Use what space you have efficiently and determine how much wall space you have to put up shelves and cases. Proper shelf depth and material will help with the lighting you want on your collection too!
