Thank you all for the comments! I almost have everything I need for the army besides Decimators and Defilers. I've been trying to build some but they don't turn out very satisfactory. So now I'm trying to learn to design them on the computer and have them printed instead. I've done a Decimator that I'm pretty happy with that will be ordered soon. I'm using Shapeways as my printer service.
Does anyone have any ideas for building a Defiler that doesn't require a ton of OOP parts?
And as a true gamer I needed to start another project and after doing some research I decided to build myself a Necron army. To make the army a bit more fun I made the Monolith and Obelisk on the computer as well and had it printed by Shapeways and they turned out just as I wanted them which surprised me as it was the first time I tried modeling anything on the computer.
