This one is more for our European readers, because this company operates out of Germany, but the Cirrus7 Nimbus is an interestingly designed, fanless system. Its fin shape is said to be assembled out of laser-cut layers of aluminum that sandwiches in the I/O plate at the rear. FanlessTech has noted that the systems are now available with Haswell processors, up to a Core i7 based on Haswell-T. Their storage options now also include the Samsung 850 Pro, up to 1TB.

The customization options are actually pretty decent. I find that a lack of meaningful upgrades to be a problem with modern PC builders, however this one does not apply. Eight CPUs are offered, ranging from a Celeron up to a 45W Haswell-T; RAM comes in 4GB, 8GB, or 16GB; up to three drives can be installed, up to one mSATA and up to two SATA; Intel Wireless N or AC is available; external DVD or BluRay burners are an option; and one of seven OSes can be installed, including two versions of Linux (Ubuntu 14.04 or Ubuntu 14.10). If you get all of the bells and whistles, you are probably up to about 3,000 USD, but you cannot expect two terabytes of Samsung 850 Pro SSDs to be cheap. It seems reasonable enough, especially for the EU. The big limiter is the lack of a discrete GPU unless you are using this device for something like audio recording, which an Intel HD 4600 can easily handle.
The Cirrus7 Nimbus is available now at their website.
