Downsizing NR200 case while keeping the same components

I bought a SFF PC with the follownig specs:

Case : Cooler Master NR200
PSU : Fractal Design ION 650w Fully Modular SFX-L
Motherboard : MSI B760i Edge Wifi DDR4
CPU: Intel 12400f + Thermalright Low profile cooler
RAM: 16Gb (2x8Gb) DDR4
GPU: AMD MSI RX6800 Gaming Trio Z 16GB
Storage: 1TB NVME

I would like to downsize (mainly the depth) for the case to fit in my carry in luggage 40 x 20 x 55 cm) while keeping the same components, the tricky bit I assume is CPU cooler and GPU size (32.4 x 14 x 5.5cm).

I'm aware that NR200 dimensions are (37.6 x 18.5 x 29.2cm) but the telescopic handle arms are taking away around 3cm in depth and I'm afraid it won't fit in the travel case.

I was hoping for Dan A4 SFX but the GPU won't fit, think of NCase M1.. what are your thoughts?
