Cameron is my new primary workstation. She is a custom-built machine with an Intel Core i7-4790K processor at 16 GB of RAM. She runs Windows 8.1 Pro with Media Center, and has a NVIDIA GTX 970 graphics card. She also has a 256 GB SSD, and a variety of drives in hot swap bays. She's fairly unique in using Cooler Master's HAF XB case, which makes her relatively portable.
