microATX 2U Rackmount Case

microATX 2U Rackmount Case

Description

This is an open source hardware microATX 2U Rackmount Case design. It can house microATX and miniITX motherboards for use as an asterisk PBX or general purpose small server. The idea behind it is that there are not many cost effective option available when you want to use a rackmount case to house projects. Existing solution are either very simple and not aesthetic pleasing or require heavy modifications and tooling to get things like lcd displays,connectors etc Also one of the requirements is for the case to be able to provide sufficient protection on a high vibration environments
