I'm completely new to building PCs and want the best gaming system I can put together for around $1,200. I already have a monitor, keyboard, and mouse, so the budget is only for the computer itself. I'd like the parts to fit an NZXT H5 case, and upgradeability matters to me. Should I build on AM4 or AM5, and what parts would you recommend?

Since you already have the peripherals, the full $1,200 can go toward the PC. I’d choose AM5 rather than AM4 because it gives you a better upgrade path for future CPUs. Prioritize a strong graphics card, then pair it with a reasonably priced AM5 processor, 32GB of DDR5 memory, a 1TB NVMe SSD, and a reliable power supply. Make sure the specific GPU length and CPU cooler height fit inside the NZXT H5 before ordering.
If the budget includes a monitor, keyboard, and mouse, $1,200 would be very tight for a new build. Since you already own those, it’s much more realistic. Used components can lower the cost, but buying new parts is simpler for a first build and usually comes with better warranties.
Don’t feel bad about being new to this—part compatibility is confusing at first. Use a parts list checker to verify the motherboard, memory, power supply, and case clearances. Also leave a little room in the budget for extra case fans or unexpected price changes instead of spending every dollar on the headline components.
