Dell's announced the Alienware Aurora R4, an update to the Aurora ALX from last year. The R4 uses the wacky chassis from the ALX, which includes controllable vents on the top, CPU liquid cooling, easy-to-replace hard drive caddies, and many exterior lighting controls. The "base" version has a six-core Intel Core i7-3930K processor that's been overclocked to 3.9GHz, 8GB of RAM, and an AMD Radeon HD 6870 GPU with 1GB of VRAM for $2,199. Pretty reasonable, but that number will quickly turn scary if you take advantage of upgrades like an Intel Core i7-3960X Extreme overclocked to 4.2GHz, dual AMD Radeon HD 6950 GPUs with 2GB of VRAM each, 16GB of RAM, SSDs, and a Blu-ray burner. You can opt for three different Nvidia graphics options as well. The whole system runs on Intel's new X79 chipset, and it can support up to six monitors at once with AMD Eyefinity. The Aurora R4 is shipping now from Dell's website, but if you're looking for some more specs, check out our product page.
