Xigmatek is not known for offering cases that use aluminum as a main material. That said, the Nebula does a good job with its three aluminum panels. The noticeable price difference between Europe and America is baffeling as the chassis for some reason costs much more in the US of A. But before we get to the topic of pricing, let us look at how the Nebula fares as an enclosure.
Starting with the exterior, the unit looks quite sleek and should be worthy of being placed next to your TV. Some people may not like the use of silver plastic as a base, but that is a subjective issue. Its three removable sides also easily allow you to assemble and access everything within the Nebula. This brings us to the interior, which is, albeit functional, quite simple. I feel as though the chassis should go for around half the US dollar price if it were only to use steel panels instead of aluminum ones, which would translate into 50 euros. So, last but not least, there is its price tag: The 80 euros in Europe are adequate - not cheap but certainly justified. I would still like to see it clock in at 69.90 instead of 79.90. I am not sure why its price is so much higher in the US as it clock in at close to 100 euros with a basic tax calculation.
The chassis looks good, is easy to work with, makes good use of aluminum, but does not offer the level of engineering internally as other manufacturers that use the same material mixture. Grabbing the chassis is then certainly a good call if you like what you see as that is one of the more important facets of a chassis for a HTPC setting.
