Dell Precision M6700 - Missing Harddrive

I have inherited an old Dell M6700 laptop and it's missing a hard drive. I'm wondering if that's the only thing it needs (other than an operating system installed) to make it functional, and if it's worth it for the ~$100?

I've listed some of the specs below:

• Processor = Intel Quad Core i7 2.6Ghz
• Memory Installed = 16384 MB
• Memory Available = 16278 MB
• Memory Speed = 1600 MHz

I would mostly be using the computer for 3D CAD programs, other engineering software, and some very light online gaming.

Thanks!
