The soft X-ray multi-camera tomography system (XMCTS) is currently under preparation for commissioning and first operation in the next experimental campaign of the Wendelstein 7-X stellarator. The diagnostic consists of a set of 20 X-ray cameras installed inside the plasma vessel. For design, engineering and manufacturing of the mechanic and electronic components extensive requirements had to be met, which are specific for operation in a long pulse plasma device. This includes for instance compatibility with high levels of microwave stray radiation, the need for active cooling and the handling of sputtering of wall material. This paper describes the final preassembly and provides a summary of major technical issues. The key work packages are the welding of the pipe systems (water cooling, compressed air, signal) and the integration of the electronic components including signal and supply cables.
