Laptop help

I figured I'd ask y'all for some advice.

Aside from the craptacular week many of us just endured w/ Ida with evacuating/being w/o power/internet for the better half of the week albeit with generator power, etc, I managed to kill my personal laptop late last week by knocking my drink over and having it splash all over the keyboard and seep into the inside. I tried my best to dry it off but to no avail, the screen kept showing that there wasn't any bootable device detected.

I took it to a local computer guy here in BR 2 days later since we spent the day after I killed it going back to NOLA to meet w/ the roofing guy/clean stuff up. He told me that the C drive and motherboard are fried but the D drive is fine. He's offering to install a new/better C drive, reinstall the D drive (he offered to replace it w/ a SSD drive w/ half the space but better performance since the one I have is a mechanical drive).

He'd charge me ~$90 for the new C drive and $190 for labor. We found a replacement motherboard on ebay for $599. So, I'm looking at roughly $880 to get it fixed, and he does a 1 yr warranty for parts/repairs.

My question is, would you guys think that spending the $880 to get it repaired would be worth it vs ponying up some extra $ to get a brand new computer for roughly $1.5k? It's roughly 3.5 yrs old and this is the model. Thanks in advance for any input.
