You could probably get paid to take away a computer with better specs.
Use the box the components are shipped in as the case.
Steal the computer mouse from the local police station for a bonus thrill.

I know, not the same, but I built my kid a cheap “Gaming” laptop from an old corporate PC that was going to be scrapped because it restarted every hour of use.
Cleaned the cooling fins and fan, repasted both cpu and gpu, got a cheap ssd and extra sodimm of ram. Was good for about a year or so until he got my Ryzen rig :)
Here’s how you build a high-spec’s top-tier gaming PC for a hundred dollars:
1 - Go to your non-local consumer electronics store
2 - Find the most miserable looking employee
3 - “Hey bro, I give you 100 bucks if you tell me your guys’ security code”
4 - Come back at night
5 - You get the idea
4 - He gives you a false code, but takes your money.
5 - You come back at night and the cops summarily arrest you.
