I'm not criticizing your project, but I do recommend that you revise your eBay listing.
"This is a VERY sturdy item, every wire, and every casing was tested to withstand any force or pressure. All because its very sturdy doesn't mean you can hold it by the corner of the screen or the audio amp."
I would take that part out since looking at it shows that it's not very sturdy. The switch for the screen is hot glued onto the outside of the console and is likely to fall off if bumped. If someone bought it and something came off, they'd have a valid case that the item was not as described, despite you saying "no returns".
Also $250 probably isn't going to appeal to many buyers, because they could buy a Nintendo switch for about that price.
It's also your obligation to disclose that the wii is missing its bios battery and tray, as that affects functionality. Whoever buys it will have to buy parts off eBay to make it a complete wii.
Like I said, I'm not criticizing your work, but if you don't describe your item accurately it could get you into trouble with eBay or leave you with bad feedback if someone buys it (which impacts your ability to sell expensive things).
