Haswell-Infused Alienware X51 R2 SFF Game PC
The downside to this design is that even something as simple as swapping out the RAM becomes a process. In this instance, the X51 R2 is rocking 16GB of DDR3-1600, which is plenty for playing games and even content creation chores. There really shouldn't be a need to upgrade the RAM unless a stock goes bad, or there's a killer sale on a 32GB kit that you simply can't pass up.
Like the first generation X51, Dell again for a half-height air cooler keep the Haswell chip humming along. In the area immediately surrounding the CPU you can spy the built-in Wi-Fi card and two naked sticks of RAM. It's a little curious that the memory modules don't have heat spreaders on them, though we'd be more concerned if this was a heavily overclocked system.
Two SATA drives occupy the X51 R2 Dell configured for us, including a Micron RealSSD C400 256GB SSD (SATA 6Gbps) for the OS and games, and a Western Digital Scorpio Blue 1TB hard drive (SATA 3Gbps, 5400 RPM) for storage duties. It's the best of both worlds, offering speed for your programs and capacity for things like digital pictures, music, videos, work documents, and so forth.
