The 2.5V1F capacitors you showed in your other post are the clock capacitors I was referring to. They help the console keep time for a little while in case it losed power. They're black on every revision except the last. The gold ones are typically more reliable and less likely to leak, but still can't be fully trusted after 20 years.
These sites should provide useful info for you to work on them:

https://consolemods.org/wiki/Xbox:Versions

These go into detail on the different revisions of the XBOX and the clock capacitor failures on the earlier revisions.

This led me down the right rabbit hole, thanks! 😁 I see the board in xbox#2 is 1.4, so it should work without the cap. I was already sticking a LED in the holes, just because. I'll leave it and read more on different failures/symptoms, I feel like it's close.

I made it to "Old New York" in the Futurama game and decided to open xbox#4. Wow. Just wow. I hadn't opened a fresh one before, so I wasn't sure how it was held together. Many more screws involved compared to these modded ones, which have NO screws... at all. The casing fits together better, too, slides right together. Actually, the whole thing is like that! It is dirty as they come, but it came apart so nicely compared to the "old wh*res", 🤣

I plugged it in with the board exposed and hit the power button and could hear a light "fizzle" sound for about 2 seconds. It would do it every time. I removed the board (another 1.6). and replaced the obvious plague crew (5x6.3V3300). I slid the board back in and plugged it in. Hitting the power button, the system now boots!

This one only has "Lego: Star Wars" on it, so I went for it. Works great and looks good, getting a bit hot, but it needs to be closed for proper cooling.

I ran Call of Duty on xbox#1 and it looked like absolute crap. Probably because I've always ran it on PC and even with the worst settings on the worst computer, it looks FAR better. Not feeling like I missed anything back then, excepting a few games.

I'm surprised the Xbox can even "run" Doom3. Doom3 was harder to get running on my PC back then... PC looks better, but I couldn't get any kind of "playable" state out of it. 10FPS with dips and freezing is what it was back then. I only had the demo for years, and when I got the full version, my PC was more appropriate (PentiumD 3.75/8800GT) and felt like it was whoopin' that game!

I'm going to properly clean Xbox#4 and replace the clock cap with a regular cap. I think, when I'm fully assembled, I'll get those caps on the A8N-SLI sorted-out...Thing has been laughing at me all week 🙁
