Said the guy who owns a £250 case.

I wish I had space for the 7000D, I'd buy one too.
But on a serious note, better to buy a 9070 now than spend the same total anyways on other stuff with less long-term value.
I needed bigger than middle tower case, because I hated to remove half of components every time I need to change something small, like a fan.
It's a really good case. You can fit 420mm 38mm thick radiator with push pull config on the top (25+38+25). Pricey but good case.
But, look, you buy case for what ... like 10 years? Case does not degrade over time like electronics. Maybe this one will last even more than 10+.
Posting update about my ASUS RX 9070 XT TUF:
Haven't had much time to test it in 3DMark. After few sessions of gaming, memory junction temp can go up to 75°C, while GPU hotspot temp is 59-60°C.
IT seems card will not ramp up fans because of high VRAM junction temp. I'm gonna try gaming at min. fan speed next time and see how temps change.
VRAM is Hynix. Fans won't start until GPU hotspot temp is below 60°C. Minimum fan PWM duty cycle seems to be 30% (~421 RPM).
Until PWM duty cycle of 42%, card remains really silent. At 30-36% not hearable. After 50% it starts to annoy me (personal thing) but it's still pretty silent.
ASUS GPU Tweak III software is ... could have been worse. Eats roughly 150 MB of memory, enables to tweak GPU voltage, power limit, freq. offset, fan curve, memory freq.
It kind of refreshes it's data maybe once in 2 or 3 seconds, so it's a bit annoying - sometimes you apply changes and see no immediate feedback.
ASUS say the software works with cards of any brand, so you can try it. I find it better than having whole Radeon driver suite eating up RAM.
For some reason, might be a bug, even when you save a profile, if you load any profile later the power limit and voltage frequency will always reset to defaults.
You have to load profile, change voltage and power limit and apply.
