Origin Genesis X99 Model
Customization is the name of the game with Origin computers, and the Genesis really shows that off. Not only are there a ton of options for you to choose from when setting up your gaming rig, but you can contact Origin to request components they don't normally carry. You're just not going to find a better level of customization unless you're building the computer yourself. Even if you do just stick with what Origin offers, the Genesis is an absolute powerhouse gaming PC.
The genesis has an Intel i7 hex-core CPU you can upgrade to an eight-core processor if you need even better performance. The default NVIDIA GeForce GTX 960 2GB video card is good, but you can upgrade it as well to a number of different setups all the way up to four NVIDIA Titan X cards. It comes with 16GB of DDR4 RAM, but you can upgrade that to up to 64GB of memory to create one of the most powerful computers you'll find for gaming.
This gaming rig comes with CPU liquid cooling, but you can upgrade to even better cooling solutions and choose a liquid-cooled video card for incredible heat management. The 650W power supply in the baseline build is a bit weak, but you can upgrade to up to a 1.5 kilowatt model. With multiple bays for hard drives and two bays for optical drives, you can build an Origin Genesis capable of taking on any gaming-related task.
