What a $1,000 PC From 2023 Teaches About Depreciation

A subscriber sent Tech Notice a PC built roughly three years ago for around $1,000. The video that followed—a 26-minute teardown and upgrade session—manages to be more instructive than a dozen build guides. Not because it shows you how to do things right, but because it documents what happens when things go slightly wrong.

The machine booted. The parts were respectable: an Intel 11400F, RTX 3060, 16GB of Corsair Vengeance RAM, an EVGA power supply, and an NZXT case that still looks clean. On paper, this wasn't a disaster. But the CPU was hitting 102°C under load, throttling performance into oblivion. The RAM was installed in the wrong slots—one stick wasn't even fully seated. Dust had accumulated in predictable places. And someone had apparently eaten lunch inside the case, leaving food debris that had begun to rust.

"Thermal paste here completely dry," the host observed, pointing at the CPU cooler. "If you look at the RAM prices, they have massively appreciated. So, are we back at $1,000 now?"

The answer, after tallying current used prices: $830. A 17% depreciation over three years. In the current market, where RAM shortages have pushed prices up and GPU values have stabilized after the cryptocurrency chaos, that's not terrible. But the number obscures the real story.

The Throttling Problem

Before any upgrades, the host ran benchmarks. The GPU performed fine at 170W, temperatures reasonable. The CPU was another matter. During warmup—before the actual benchmark even started—temperatures climbed to 96°C. When rendering began, the system hit 102°C and throttled immediately, pulling power down from 93W to 60W just to stay alive.

"We got to see some thermal throttling in a minute now," the host said as temperatures climbed. "So, basically, when you see red, it's bad. And it's pretty red in here."

This is what theoretical performance looks like in practice. The 11400F is a capable chip. The RTX 3060 remains a solid 1080p card. But pair a decent processor with inadequate cooling, and you've built a machine that advertises capabilities it cannot deliver. The owner paid for performance that thermal physics prevented.

The fix: a DeepCool AK700 cooler, two additional case fans, fresh thermal paste, and proper cable management. After the upgrade, the same CPU under the same load peaked at 60°C—a 42-degree improvement. The system stayed quiet. Performance remained consistent. The difference between 102°C and 60°C is the difference between a machine that works and one that merely functions.

The RAM Surprise

Here's where things get instructive. After moving the RAM to the correct slots and updating the BIOS through six versions, the host discovered something: the Corsair Vengeance kit wasn't on the motherboard's qualified vendor list. The RAM was rated for 3600MHz. The system would only run it at 2133MHz.

"You've paid for 3600, but you're never going to get it," the host explained. "So, you might as well sell it, get something else, or you're just going to have a nice flashy RAM."

This is the gap between building a PC and understanding compatibility. The RAM works. It boots. Games run. But you've left 40% of your memory bandwidth on the table because you bought components that don't cooperate. DDR4 was supposed to be plug-and-play—and mostly it was—but "mostly" is where money disappears.

The broader lesson: component compatibility isn't binary. Things can partially work. They can function without performing. And unless you benchmark, you won't know the difference.

What Depreciation Actually Measures

The $1,000-to-$830 calculation is straightforward arithmetic. But it doesn't account for the performance the owner never received. The CPU ran hot for years, likely degrading silicon with every thermal spike. The RAM underperformed from day one. The GPU was fine, but it was working inside a thermal disaster zone.

What's the depreciation on performance you paid for but never got?

The RAM shortage has created an odd situation where memory has appreciated while GPUs—which typically hold value better—have fallen. The RTX 3060 launched at $329 and now sells used for roughly $200. The Corsair kit that originally cost around $80 is worth more now due to supply constraints, even though it never performed to spec in this system.

This creates an illusion. The $830 valuation suggests the owner lost 17%. But factor in the incompatible RAM, the thermal throttling, and the missed performance, and the real depreciation is steeper. You can't sell performance you never had, but you definitely paid for it.

The Maintenance Tax

The video spends several minutes on cleaning. Dust in the filters, debris in the case, dried thermal paste, food particles on the GPU backplate. This wasn't neglect—most PC owners never open their cases after the initial build. But that approach has costs.

The difference between a maintained PC and an ignored one compounds over time. Dust reduces airflow. Degraded thermal paste raises temperatures. Higher temperatures reduce performance and lifespan. The system works, but it works worse each month, so gradually you don't notice until you benchmark it.

The host's upgrade—about $80 for a better cooler and two case fans—transformed the system. But it also highlighted that the original build underinvested in thermal management. The stock cooler was always inadequate. The single exhaust fan was never enough. These weren't problems that developed; they were problems that shipped.

PC building enthusiasts often focus on the dramatic choices: which GPU, which CPU, how much RAM. The video suggests the boring choices matter more. Adequate cooling. Compatible components. Cable management that allows airflow. The things that don't show up in spec sheets determine whether your theoretical performance becomes actual performance.

The PC that someone built for $1,000 three years ago is worth $830 today, possibly more with the cooling upgrade. But the more interesting number is zero—the cost of checking motherboard QVL lists, installing RAM correctly, and budgeting for thermal management from the start. That's the depreciation you can actually control.
