Custom Build Computer Tower

Honestly I am not an educated computer tech person - I asked a good friend of mine to build me a desktop computer to use at home to work on my side business as a civil engineer. He’s an avid PC gamer and computer whiz so I trusted him. I needed a setup that could handle large design drawings and models in AutoCAD Civil 3D. He built this for me last year with all custom parts but now my work is giving me and even better setup and I have no more use or space for it. It has a lot of memory and RAM, more than enough to handle the 3D modeling rigors. The graphics card is also excellent to handle the program. Sorry I can’t be more descriptive. I paid $1,000 for the entire setup (with 2 monitors). Comes with keyboard and mouse also.
