Hey Kenshin.
If you really want something to stand out, try handpainting the cases...create a stencil in photoshop or something then apply it to a casing and hand paint it. Colour will stand out a lot more and it looks less tacky. Thats my opinion at least.
Cant think of any graphics to suggest to you, but i can say that i think if you made the acidmods text glow in the dark that would be cool

By the way i got an awesome pic of a hand painted 360 i can show you on msn, just hit me up next time you see me on there.
