You can use an empty mechanical pencil to straighten them. I would return it for a refund and never buy from there again, but that's just me.

Re: Why moving to 64bit?

You're only supposed to use hardware a year or two then throw it away. i686 is on the support chopping block and it wont be long until 32-bit ARM is too.

Re: 5v on GPIO to power I2C board

Yes, as long as they don't take too much power. Generally it is also safe to power the Pi through those pins, but you have to take in to account that there is no fuse if you do it that way (Pi 0 and 4 don't have fuses anyway). The official PoE HAT powers the Pi 3B+ and 4B through those pins. With i...

5v on GPIO to power I2C board

It is safe to use the 5v GPIO pins for powering other devices such as an I2C board, correct? The only issue is when trying to power the Raspberry Pi directly through these pins? I do not want a fried Pi.

There's your problem. Even with no case and a tiny heat sink, I've seen mine get up to 75C under heavy load. If you had yours in there, it was probably throttling nonstop.

It's not even a challenge anymore. Read write speeds and Ethernet weren't quite up to snuff on 3. All of my programs that I use on PC run perfectly fine on 4 at 6 watt maximum as apposed to 110w. I grabbed a 512GB Samsung microsd card for the occasion .
