| If you are a designer, this is absolutely the best thing you can do to sky-rocket your market value over night: Create a concept design from a popular product and put it on a slick landing page. It shows that you, as a designer, are proactive and think beyond designing standard stuff (like webpages or mobile apps). Moreover, you are not limited by any client restrictions[1] which hurt your work (and portfolio), you learn 3D modelling if you haven't yet (it's not hard just time consuming), if you are lucky with social news sites you get so much free promo and finally, it's the eye-catcher on any CV.

But you must still limit yourself to sanity and physics. Too often, designers don't have a clue what's actually going on behind the scenes, and embarrass themselves.
This example puts 16 TB3 ports on a computer, because "consumers want it to be very expandable" and "2 columns of 8 looks pretty". It also adds two graphics cards but buries the connectors into the floor rather than making them externally accessible.
Concept cars by designers may have faults such as zero visibility from the drivers seat, have aggressively high front bumpers and low hood lines that look designed to kill pedestrians, utterly lack necessary things like exhaust pipes, crumple zones and spare tires, or have absurd specifications ("500 miles from the 2 cubic foot battery pack!" "600 HP V12 under the rear seat!")
Your target (other marketing departments) may not care. But it's also very possible that they encounter these limits as a part of their daily work, and will care, judging you for your lack of domain knowledge. Definitely create some concept work for your portfolio. But don't stray too far from the realm of the possible.
