Custom LEGO builds
You can buy both kits here: https://powerpig.ecwid.com/
The builds are very well documented (build guides) and it is really fun building. I actually did it together with my wife this evening. The internals of the PC and the burger are very well build and you actually build stuff that can never be seen from the outside. I like that.
The only downside might be the high cost of the builds as I had to pay import tax on the package. Anyway it was a lot of fun and having this small computer and burger really is fun 🙂
