I have no idea about how good your bundle deal is.
But, as a general rule, when buying new, I would look at 13th gen.
For example the I5-13500 performance is similar to the 12700K and should be cheaper.
Nothing wrong with a Z690 motherboard.
It does permit overclocking of a K processor.
But, overclocking these days is not what it used to be, namely free performance.
Parts are binned so there is little headroom.
Today, the stock turbo mechanism works out better.
And, If budget is a concern, look a B660/B760 MATX sized motherboards.
Fwiw, your case is a good one for air cooling; a Noctua NH-D15s would cool about as well
as the Z63. But looks do count so it may be worth it to you.
