I second the motion towards NR200p which is the case I have now.
Only thing to be aware of with the NR200p is there is less space for big air coolers than the TU150. However, if you look through the massive NR200 thread you will see plenty of working examples using the Scythe Mugen 5 or Fuma 2. Just check which motherboard people are using with these to get them to fit without issues.
Also note there is no USB-C on the front IO of the NR200P. If that is a deal breaker, then the TU150 is still a good choice.
NZXT H210i? What level of components do you intend to be using?
The TU150 isn't great for water cooling. Max size is a 120mm radiator.
I don't suppose using a USB-C hub connected to the Motherboard rear panel is an option? I feel the advantages of the NR200P (size and component compatibility) outweigh the need for a front USB-C.
In stock right now, nope. A competitor has the white case due on January 5th though if that is a preference.
It is a hard one as I know you are probably wanting to get on with it now.
Like I said, the TU150 is still a strong contender, but I would go for an air cooler. You can fit the Noctua U12S or even the D15 in the TU150 which sets it apart from the NR200P (using tempered glass side panel).
TU150 is a really good case. It's just one of the many ITX cases which could have been great if the manufacturer hadn't included a silly gimmick.
In this case, it's the handle.
They could have made it a good bit shorter, or could have added 240mm or maybe even 280mm rad support if they hadn't added a handle which almost nobody will actually use.
Still really good for what it is though. And it's arguably a better looking case than the NR200.
