Origin's new Battlebox PowerPC has a GeForce GTX 780 graphics card which is perfect for new games such as Call of Duty: Ghost and the new Watch Dogs that will be coming out for the holidays. While you have the option to upgrade the graphics card these are the specs for the Battlebox:

Case: Corsair 500R 
Standard Case Fans
ASUS Z87A
ORIGIN FROSTBYTE 120 Sealed Liquid Cooling Systems
Intel Core i5 4670K Quad-Core 3.4GHz (3.8GHz TurboBoost), 6MB Cache
650 Watt Corsair RM650
Dual 3GB EVGA GTX 780
16GB Corsair Vengeance 1600Mhz (2x8GB)
Genuine MS Windows 7 Home Premium 64-Bit Edition
500GB SATA 6.0Gb/s, 7200RPM, 16MB Cache
ASUS 24X CD/DVD Burner
 

While this might be a "screaming" PC in some sense it lacks a few essential components for gamers. Origin could have added better case fans (ie Noctua) to achieve even better cooling on top of the liquid cooling for the Haswell Intel Core i5 4670K processor. Since we are on the topic of the processor, it is only a Core i5 and gamers alike dont want an expensive $2000+ system if its not a Core i7 at least. In addition you would need a higher power power supply to support two if not three 3GB GTX 780 graphics cards. 

On the other hand a 500GB SATA 6.0 hard drive will support a number of games but a SSD would have a much faster response time than any hard drive on the current market. Lastly the price of $600 for building and checking performance is a little ridiculous. Im sure many enthusiasts and other custom PC builders could build it with a lower price tag (*hint *hint).
