Hello, loving my new Dan A4 build!

I love my Dan A4 build, just have some slight issues I've come here to get advice on! I really like that I maxed out transportability, since I fly for extended trips a few times per year.

If anyone is curious, my important specs are:
ASUS B550 Strix ITX
5600X
RTX 3070 (Zotac Twin Edge OC)
Corsair SFX 600W Platinum
Corsair 16GB 3200MHz Memory
2TB Samsung 970 EVO Plus M.2
