If you decided to bite the bullet and swap your gubbins across (which is a giant piece of wee-wee anyway), you'd have a box that's so easy to work on in future that even a thicker-than-average monkey can easily perform upgrades. After all, it's absolutely cavernous inside and pretty much tool-less. To buy an equivalent box, once these sell out just before you eventually realise that all this makes perfect sense, you're going to have to find a lot more dosh (circa a ton more) than they're asking for this.
Just think about it: a bit of pain today, in return for a far easier life in the foreseeable. Plus, with a case like this, people will think you're a demi-god and scatter rose-petals in your path when you go shopping.
