The fellas over at techPowerUP had a lot of nice things to say about the Jonsbo UMX4 computer case they just reviewed. While I don't have any firsthand experience with the UMX4, it sure is a nice looking chassis.
The UMX4 utilizes thick aluminum and glass (in case you opt for the windowed version) and is available in anodized black or silver. Jonsbo aims the chassis at those who put design and construction quality on the very top of their list. We are reviewing the Jonbso UMX4 in silver and with the window today.
