Nice price for a configured emulation system with AmigaForever included to make it all legal. How is the performance on these systems (not that I am interested in buying one, as I already have way too many computers, and regularly run AmigaForever on my i7 laptop), plus can you provide a picture, or a link to a picture.
I think a lot of users prefer to have someone else find off-the-shelf hardware that works well and do all the installation and configuration for them, so all the buyer has to do is pay for it, plug it in, and turn it on. If you are also offering a service to configure these systems with custom workbench and legal software packages preconfigured, that should be popular with new users who are not experienced in setting things up themselves on an Amiga system.
Good luck with this nice idea. It isn't what most experienced Amiga users probably want, as they usually customize their own systems, but for some users, your end product and custom services will probably be appealing.
