What sets the Genesis desktop computer apart from the competition is its flexibility. When you purchase one, you can decide how you want the case to be oriented, for example, and you can choose whether you want the front door, which gives you access to give hot-swappable drive ports, to open on the left or the right. You can choose Intel quad-core i5 or i7 processors. A steel chassis supports up to 34 hard drives, 64 GB of memory, and up to four graphics cards, not to mention an array of cooling options.
