no aurender does not make upgradable hardware
Most streamers and servers are based on a single board with a chip based processor like an arm or veracite cpu and another set of chips which contain the operating system.
other servers servers are more like a custom computer:Innous Wolf Baetis432EVO
We import a line of completely modular servers 432EVO which are upgradable because they are fully modular no single board design
Instead we have a cpu board an ssd for the os and music storage and we have a separate soundcard and clock board so this design allows you to improve performance as new parts come out.
