My roughly 10-year-old PC has stopped working, and after troubleshooting I suspect the motherboard has failed. Repairing it no longer seems worthwhile, but I currently have a very limited budget and need a working computer immediately for a DaVinci Resolve video project and multitasking.
The old system used an Intel i5-6402P, Radeon RX 460, and 16 GB of DDR4 RAM. My idea is to buy a case, motherboard, CPU, and a reliable power supply now, while reusing the RX 460, 16 GB of DDR4, and possibly the existing hard drive containing my project files. I only need performance roughly comparable to the old system for the moment.
In about 6–12 months, I expect to build a much stronger workstation and gaming PC, likely with 32 GB or more of DDR5, a newer graphics card such as an RTX 5070, and a budget around $2,000. Is there anything I should prioritize now so I avoid compatibility problems or wasting money later? Would it make sense to buy a particularly good motherboard or power supply now and reuse it in the future, or should I treat this entirely as a temporary build?

Another practical option is to buy a complete used or refurbished system rather than selecting a new motherboard and CPU separately. Since the whole machine is temporary, the best choice is whichever route gives you the lowest reliable cost. Get enough performance to finish the project, keep the case and PSU reasonable, and plan to resell or repurpose the bridge system when you build the DDR5 machine.
A used AM4 setup could be a good low-cost bridge. Something like a Ryzen 5 2600, 5500, or 5600 with a B450 or B550 board should work with your existing DDR4 memory, RX 460, and storage. AM4 also has worthwhile later CPU options, including the 5700X3D or 5800X3D for gaming, although you would still need a new motherboard and DDR5 memory when you eventually move to a newer platform.
The power supply is the part worth carrying over. Buy a reputable model with enough capacity for the eventual graphics card—around 750–850 watts if that fits your future plans—and modern PCIe/GPU power support. Do not overspend on a premium motherboard that will become obsolete with the next platform. A reliable, inexpensive board is enough for a bridge machine.
A motherboard bought for a DDR4 system generally will not carry over to the DDR5 build you are planning. DDR4 and DDR5 use different slots and platform requirements, so choosing DDR4 now usually means replacing the motherboard and CPU later. If you cannot afford the final system today, a temporary build is reasonable—but assume those parts will be sold or replaced rather than trying to future-proof the platform.
You can reuse the hard drive to access the project, but do not rely on it as your only copy. Older drives can fail, especially after a system dies, so back up the project before rebuilding if possible. A small SSD for the operating system and active project files would make the temporary PC feel much faster, while the old drive can remain secondary storage.
AM4 is still perfectly usable for a temporary or budget system, and a suitable used CPU may even include a cooler. Just compare used prices carefully, since an inexpensive older system only makes sense if it is substantially cheaper than newer options.
