With the Xigmatek Asgard Pro selling for less than 40 Euro, the case turns out to be more affordable than the Asgard 381, but the Asgard Pro includes more I/O, a second fan, and better overall construction quality. On the other hand, the Pro goes for 45 USD, while the 381 clocks in at 40 USD in the US of A. That said, the Asgard Pro is not as flashy as the 30 and is clearly aimed to deliver great value to those who prefer understated and timeless cases, and at the given price point, one cannot find a lot wrong with it. On the contrary, the case offers a dedicated 3,5" bay, which is a great sight to see, plenty of space for most scenarios, and the ability to circumvent the somewhat inadequate locks within by using traditional screws.
The case manages to impress at a great price point, and you do get a lot of bang for your buck with the Xigmatek Asgard Pro, so grab it if you want the most out of a case and are on a slim budget.
