My house burnt down last Sunday night and I lost my gaming laptop...what should I do?

So, long story short my cousin gave me his old gaming laptop, it was a predator--not sure what model--and I had 16 GB of DDR4 ram, an NVIDIA GeForce 1660Ti, and around 500 GB of SSD. I lost it and all of my other consoles as well. I want to replace it ASAP. Now, I wanted to ask for opinions on whether or not it would be best to buy parts and build my own or buy something different. I need to know what would be the cheapest way to just replace what I had without spending a fortune with what little money my family and I have right now. Thanks for reading, anything helps!
