I stopped thinking for a minute or two...now I DESPERATELY need help!!!

I'm very stressed, in a very hot and humid room, and am on my phone, at 12 am, so I wont write much, and will instead respond to you guys if possible.

To make a long stories short I'm building PC for a friend (Ive built many, like 20+), and have made the worst mistake I could have.

His initial budget was $800 CAD, but after hearing the amount in his bank, I lowered it to $500 CAD. Things have been going well: I got a good deal on PSU ($40), got a really good deal on a 5500 ($80), found RAM that wasn't above $200 and was 16gb+ ($50), and already had an SSD I could use had a boot drive. HERE'S THE ISSUE, I saw an ad for a am4 motherboard for $75 and overpriced 1660 - I managed to talk the mb guy down to $65, and 1660 guy to giving me another 1660 he had and case for $200...

Thats the issue, by underpaying for so many items, I felt emboldened to overpay for a known working GPU, and case that should be in a land fill - I also live in a city whose tech market is dog.

Here's the thing, that $65 mb had an issue, a latch issue, and so, like I have done before, I superglued it...it melted and leak...now my the 5500 that I got a good deal on is stuck...

I have given up on the motherboard...

How do I get it unstuck?
