Indeed. But alerts would be a nice addition to expert mode anyway. You can't build a PC with a processor that does not fit in the socket, expert or not. Pre filtered list of motherboards or cpu based on selected cpu or motherboards would be nice. Anyway, great website.

Can someone tell me what he used to code that website? Javascript and bootstrap or something else?

Have you used BuiltWith? Looks like asp.net, jquery, bootstrap, and what not.

There's a chrome extension too.
