You could call it an Alienware PC.
My question: Would it be ethical for you to represent it as an Alienware PC, and sell it as an Alienware PC by purposefully attempt pass it off by changing the appearance to make it look like an Alienware PC?
To add to the gray area:
Say DELL XPS 1000 and Alienware 90210 are essentially the same machine, save for custom tuning, drivers, and cosmetics. Alienware gets a 25% markup.
You have the XPS 1000, apply the custom tuning and drivers to get the performance of the XPS to that of it's Alienware's counterpart.
Could you sell it for more than the market rate for a use XPS1000? Yes. I'd argue you have added value by custom tuning the PC. But I believe responsible to disclose that it was an XPS that had been modified.
Taking this back to cars. If an when I sell my Golf R, I will disclose it has received a Stage 1 Turbo upgrade (and hopefully use that to increase the resale value--though it typically does not except to other enthusiasts).
