Corsair One I300

So if the price in your region makes sense at the time of the purchase or if Corsair kind of decides to adjust the price to the new GPU pricing it is ...

Money is an issue The Corsair One i300 is expensive. Very, very expensive. For many people, this will make it impossible to justify

You get ALL of the benefits of a prebuilt, but you save money, get better specs and get a MUCH higher quality PC (because prebuilts are pretty universally low-to-trash-tier quality devices). There are exceptions - boutique stuff where they use off-the-shelf components but do cool stuff to it or unique form-factor stuff like the Corsair One (that actually uses decent components). Those are rare though.
