Today I put together an XP gaming system. Specs are overkill, but it's what I have at hand:
i7 2600
4 GB RAM
250 GB SSD
GTX 680
Method I used for installing XP and updates is a bit different from others in this thread:
Easy2Boot - Creates a bootable USB that allows booting of ISO files similar to Ventoy. I used an untouched XP SP3 ISO, and it slipstreamed the AHCI drivers live. The website is a bit overwhelming with information, but it wasn't too much trouble to figure out how to use. PhilsComputerLab has a video that covers using it to install XP:

Legacy Update - Allows installing updates for XP, including the extended life updates.
Snappy Driver Installer - I manually installed my NIC and GPU drivers and used this tool to install the rest.
I grabbed some ISOs for American McGee's Alice from archive.org. Installing the game was a real blast from the past. I used DaemonTools to mount the ISOs and bypass the SafeDisc protection without needing a NoCD crack. Also, had to search for serial code to install it, and one of the first hits was a non-HTTPS site on a free web host. Had serials for a bunch of other games from that era, such as Starcraft and Diablo 2. This is making me feel 20 years younger!
