For most of the twenty-plus years I've been doing this, the answer was automatic: yes, building your own PC saves money over buying one. In 2026, I have to give you a different answer, and I'd rather be straight about it than repeat advice that stopped being true. Right now, on raw parts cost alone, building it yourself often does not beat a comparable prebuilt. Here's why — and why custom builds are still what I'd put my own money into.
The AI datacenter buildout is consuming the world's memory supply. Samsung, SK Hynix, and Micron — the only three companies that make DRAM — shifted production toward high-margin AI memory, and consumer RAM prices went vertical. Tom's Hardware's daily RAM price tracker documents the damage: a 32GB DDR5-6000 kit that sold for roughly $90–120 in mid-2025 now runs $300–500 on a good day. DDR4 didn't escape either — 32GB kits that were $60–90 are now $150–180. TrendForce's contract-price data showed DRAM jumping 55–60% in the first quarter of this year alone, Gartner is forecasting 80% DRAM and 202% NAND inflation for 2026 — they coined the term "memflation" for it — and the analyst consensus says meaningful relief doesn't arrive before late 2027. SSDs ride the same NAND squeeze, with contract prices up 33–40%.
GPUs took a smaller but real hit: TechSpot's ten-region pricing study found RTX 50-series street prices up an average of 19% in three months — in November 2025, $1,000 bought an RTX 5080; by February it bought an RTX 5070 Ti.
Here's the part that flipped the answer. Dell, HP, and Lenovo buy memory on long-term contracts negotiated before the spike, so their input costs lag the spot market you and I buy from. They've announced system price increases of 15–20% — real money — but when a retail DDR5 kit alone has tripled, a 15–20% bump on the whole box can still land below the sum of today's retail parts. Run an identical spec through PCPartPicker and against a big OEM's configurator right now and the OEM wins more often than any point in the last two decades. That's not marketing. That's just where the market is.
What the spec sheet comparison hides is what's actually inside the box. Hardware outlets that tear down mass-market prebuilts keep finding the same pattern: the CPU and GPU match the listing, and the savings come out of everything you can't see on a spec sheet — proprietary power supplies you can't replace with a standard unit, bare-minimum motherboards, single sticks of RAM running half-speed in single channel, cases that choke airflow. I see the results on my repair bench: I wrote up the five most common prebuilt failures because they walk through my door weekly.
A custom build buys you: a name-brand PSU that protects everything downstream, a board with the VRMs and ports to survive an upgrade or two, dual-channel memory actually running at spec, standard parts that any shop — or you — can service in five years, a clean Windows install with zero trial software, and in my case, a machine that ran a 24–48 hour burn-in before you ever touched it, backed by someone local who answers the phone. My take on why I don't like prebuilts goes deeper, but the short version: you're not paying more for the same computer. You're paying for a different computer that happens to share a spec sheet.
If your absolute ceiling is the lowest possible price on a given spec, this is genuinely a moment where a prebuilt can win — I won't pretend otherwise. If you have working DDR5 already, hold onto it; replacement cost is only going up. And if you want a machine built to last, built serviceable, and built by someone who'll still be here when it needs attention — that's a custom PC build, and I'll quote it against the market honestly, including telling you if a component price is spiking and worth waiting out.
