Agree with Zoolook. Not really a fan of the Alien ware rigs, over priced for the hardware. As others point out it is also likely to be a bit more expensive to roll our own rig. That said and understood, you control the quality and the build. I just built a new computer to replace the one I built near ten years ago. I used the best in class parts at the time including a server mother board and processors, reg ecc memory, and water cooled dual video cards, processors, and chipset. The entire build cost me just under $4,000.00 in total. This sounds expensive until you remember that I used it without issue for just under TEN years. My latest rig is also water cooled and with all parts, not bleeding edge but just under it I am in for around $3600 USD. I have a 4K, 40" monitor and can push world of tanks at 4K with everything cranked at 60FPS from a single GTX980SC card. I have the option of a second card to extend the usable life of the box. Another option that can be had for reasonable is the likes of an HP Z800 work station used. These usually can be gotten used off lease for less than a few hundred dollars, come with at least 8-16GB of RAM, have an LSI SAS/SATA RAID controller on board, are modular and tooless. I got one off Ebay for less than $510 with dual Quad core 2.4GHz Zeons, 96GB of RAM, two 1TB 7200RPM drives, a Quadro 2000 video card and a windows 7 pro 64bit key. Threw in a GTX960 card and it is a great work and gaming computer for under $750 USD. Throw in the fastest pair of Zeons 3.6GHz the thing will take for another $150 and swap out the 850Watt PS for the 1100W unit and you are still under $1200 for a rocking rig that will likely keep up with most desktop machines for at least the next 5-7 years.
