I just got an OG Xbo. Now what?

I'm aware that the Xbox modding scene has been around basically as long as the Xbox. So I'm sure there are dozens of ways to mod this beast but it's 2025 and want to know what the best way to go about that is.

I've looked into both soft and hard modding and, from what I've read, hard modding seems to be the way to go (correct me if I'm wrong). What do I need to know and how should I approach this project? I don't have any soldering skills but I'm hardware adept and might just take it up to do this mod.

TIA for your time and effort
