How to phrase this: I’ve upgraded the power supply and hard drive to a Seasonic 850W and an Acer 7000 2TB, adding an extra $1000 to the build. It’s tempting, but should I still hold out for the 618 sale?

First revision: Swapped out the power supply, hard drive, and case with the Lian Li 216, bringing the total increase to over $1000.
I’m considering changing the cooling system but haven’t decided yet. I was eyeing the Kurio V2 Performance Edition air cooler, but it’s unavailable at the store. Now I’m wondering if switching to a water cooler might be noisier than expected.
Second revision: Ultimately, I went with the Titan SJ-A080 360mm water cooler for the cooling upgrade.
At this point, there won’t be any more changes—my budget has already surpassed $3000, now sitting at a whopping $12k. [Facepalm]
