I'm putting together my first PC and plan to build it myself. Because of my income and living situation, I'd prefer to spread the cost over a few months instead of making one large purchase. Is that generally safe, or is it better to save up and buy everything close together?
I'm buying the parts in New Zealand and want to keep the initial build under $2,000 NZD, excluding the GPU. I plan to use the Ryzen 5 7600's integrated graphics until I can afford a dedicated GPU. So far, I've bought a 1TB Samsung 980 Pro SSD and a Lian Li Vector V100R case. I'm still looking for a Phanteks AMP GH 750W PSU, Gigabyte B650E Eagle WIFI6E motherboard, RAM—ideally a 16GB kit—and a Ryzen 5 7600 CPU. I'd appreciate advice on the risks of buying parts separately, sales, warranties, and timing.

Prices and product availability change constantly, so don’t feel obligated to buy every part immediately unless you’ve already finalized the build. Watch for worthwhile sales, but avoid buying a component months early just because it’s discounted if you won’t be able to test it. The CPU, motherboard, RAM, and power supply are especially useful to purchase close enough together that you can assemble and troubleshoot the system promptly.
You can spread out the purchases, but buying everything within a shorter window is safer. If a component arrives dead or develops a problem, the retailer’s return period might expire before you’ve assembled the PC and tested it. After that, you may need to use the manufacturer’s warranty process, which can take considerably longer.
Buying separately can work, especially when a major expense would strain your finances. The downside is that prices could drop, newer parts could become available, or a component could sit unused while its return period runs out. On the other hand, waiting too long can also cost more if prices are rising. Track the total cost and only buy early when the discount is substantial and you’re confident the part fits the final plan.

That makes sense. I’ll try to keep the remaining purchases closer together so I can test everything before the return windows end.
