"Home" offices will not be interested in this equipment since a long time wakes up to missing a ready solution to meet their needs and in mind the reluctance of system administrators to try something new, it is easier to justify to the employer of buying one expensive but powerful hardware, and less hassle with bugs.

Features for mini server of the roof, and not all functions can handle LeMaker Guitar at the proper level, and some may not cope.
But the ability to develop modules for specific tasks (with Guitar hardware accelerators or system requirements for specific tasks) and set one Base Board is a good idea which can convey to the consumer.
And here need a ready-made software solutions with centralized management (System administrators are very lazy people).
Not unimportant question of the connection of various devices and storage media to which access is needed not just individual modules but also the group of modules.
I think you should choose option in which the Base Board can be connected number of modules for executing those functions which can handle LeMaker Guitar + 1 for the future.
