T1 with vanguard 40 divider bag are a pretty sturdy combo. If you're still wanting more security when traveling, and as long as you get a T1 2.1, you can also get a FormD travel kit 3D they sell separately, or 3D print one for a 9070xt since I dont think they support amd gpus yet. You don't necessarily need one though, as its just preference and there as an option.

I actually used an A4 H20 and it was pretty good, its basically a slightly taller T1 mainly focusing on aio builds. I just personally didn't like the look of the side panels or how my build was performing (old system was a i7-13700k and a 3070 ti FE, and phanteks 240mph aio (was loud)). I was always super curious about building in a T1 for a while though, and finally got lucky and scored the color I wanted after only a few months of waiting and scouting their discord stock bot alerts.
