Now I'm looking at a Corsair ONE...not an AIO...but still pretty damn expensive at $2,000+ for a good setup.
Add hundreds of dollars more for a 4k display on top of it...
Who the hell knows anymore...
But one thing is for sure. You really don't save much money trying to build your own system these days. It really is starting to make sense to buy something pre-built, but something you CAN mod yourself later.
Unfortunately, the Corsair ONE, while a very nice machine, doesn't lend itself, due to the small case, towards friendly, end-user upgrading.
Do I really need a GTX 1080 Ti?
Probably not...the question becomes, save money today and upgrade sooner down the line, or spend more money today and give yourself another year or two with the original configuration?
Who the hell knows?
