The 2026 Reality: Buy Less Pi Than You Think
Raspberry Pi is in the middle of a memory-price crisis. Raspberry Pi Ltd has pushed through several memory-driven price increases across 2025 and 2026, blaming the cost of LPDDR4 memory being pulled into the AI data-center buildout. The 16GB Pi 5 has gone from $120 at launch to $305.
Good news: the scalping and shortage era of 2021 to 2023 is over. Boards are in stock. Bad news: the sticker price on the higher-memory models is ugly. The move is to buy the smallest board that does your job, not the biggest one you can justify.
Our Picks at a Glance
- Pi-hole only: Raspberry Pi Zero 2 W ($15). Sips power, does the job.
- Pi-hole + WireGuard VPN: Used Raspberry Pi 4 (2GB). Real Ethernet, cheap on the second-hand market.
- Full privacy home server: Raspberry Pi 5 (8GB, $175) with an active cooler and an NVMe SSD on the M.2 HAT+.
- Heavier self-hosting or a real NAS: Skip the Pi. A used mini PC gives you more power and x86 compatibility for the same money.
Match the Board to the Job
Before you buy anything, decide what the box is for. Every privacy project on this site has a comfortable minimum, and overspending on RAM in 2026 is how you set money on fire.
| Project | Minimum board | Accessories that matter | Guide |
|---|---|---|---|
| Network ad-blocking | Pi Zero 2 W, or a used Pi 4 (2GB) for wired Ethernet | Genuine microSD, 5V PSU | Pi-hole guide |
| Home VPN server (WireGuard) | Used Pi 4 (2GB) for the Ethernet port | Genuine microSD, official PSU | WireGuard guide |
| Pi-hole + WireGuard + light apps | Pi 4 (4GB) or Pi 5 (4GB) | Active cooling on the Pi 5, quality microSD or SSD | Home server guide |
| Full privacy home server (Nextcloud, more) | Pi 5 (8GB) | Active Cooler, M.2 HAT+, NVMe SSD, official 27W PSU | Nextcloud guide |
| Light NAS / bulk storage | Pi 5 (8GB) for a couple of drives, otherwise a mini PC | Powered USB or NVMe, separate disk power | NAS buy vs build |
Current Board Prices (July 2026)
These are the direct prices from Raspberry Pi and authorized US resellers such as PiShop. Add a case, cooling, a power supply, and storage on top.
| Board | RAM | Price | Best for |
|---|---|---|---|
| Pi Zero 2 W | 512MB | $15 | Pi-hole, single-purpose jobs |
| Pi 4 (3GB, new SKU) | 3GB | $83.75 | Wired Pi-hole + WireGuard |
| Pi 5 (1GB) | 1GB | $45 | Tight-budget headless services |
| Pi 5 (2GB) | 2GB | $65 | Pi-hole + WireGuard |
| Pi 5 (4GB) | 4GB | $110 | Small home server |
| Pi 5 (8GB) | 8GB | $175 | Full home server, sweet spot |
| Pi 5 (16GB) | 16GB | $305 | Overkill for most privacy work |
The 1GB Pi 5 stayed at $45 through every price hike because it barely touches the memory that got expensive. The 16GB climbed the most, over 150% above its launch price.
Board-by-Board Breakdown
Raspberry Pi Zero 2 W: The Pi-hole Special
Why it wins: At $15 the Zero 2 W is still the cheapest sane way to run Pi-hole. It has a quad-core 64-bit Arm Cortex-A53 at 1GHz and 512MB of RAM. Pi-hole barely notices the load, and the board draws roughly 0.5W doing it, far less than a Pi 4 or a spare PC left running.
What to watch
- No Ethernet port. It is Wi-Fi only (2.4GHz). For an always-on DNS server, wired is more reliable. If you want Ethernet, buy a used Pi 4 instead.
- Tiny footprint means tiny connectors: you need a micro-USB power lead and a mini-HDMI adapter for setup.
- 512MB is fine for one job. Do not try to also run a VPN, Nextcloud, and a media server on it.
Raspberry Pi 4: Still the Value Play for VPN and DNS
Why it still matters: The Pi 4 has a real Gigabit Ethernet port, which makes it the honest choice for a home WireGuard server or a wired Pi-hole. WireGuard on a Pi 4 pushes hundreds of Mbps, enough for most home connections. The chip is a few years old but nothing about DNS filtering or a VPN tunnel is demanding.
Pricing note
- Raspberry Pi added a new 3GB Pi 4 at $83.75 in April 2026 to dodge the worst of the memory-price jump. The 8GB Pi 4 has climbed to $165.
- The used market is where the Pi 4 shines. People upgrading to a Pi 5 dump their old 2GB and 4GB boards cheap. For Pi-hole and WireGuard, a second-hand 2GB Pi 4 is all you need.
What to watch
- The Pi 4 runs hotter than you expect under sustained load. A heatsink or a small fan is worth it if the board lives in a closet.
- It uses a USB-C power input but predates the Pi 5 power weirdness. A quality 5V/3A supply is fine.
Raspberry Pi 5: The Home-Server Board
Why the 8GB is the pick: The Pi 5 is meaningfully faster than the Pi 4 and, importantly, it has a PCIe lane. That is what lets you bolt on a real NVMe SSD and stop booting off a fragile microSD card. For a full privacy home server running Pi-hole, WireGuard, and Nextcloud together, the 8GB Pi 5 at $175 is the sweet spot. Buy the 4GB ($110) if your budget is tight and you are not running heavy apps.
What to watch
- Power is a real gotcha. The Pi 5 wants a 5V/5A supply and negotiates for it over USB-C Power Delivery. If it does not detect a compliant 5A supply at boot, it caps the USB ports at 600mA, which starves any drives you plug in. Use the official 27W supply and stop guessing.
- It needs active cooling. Under load the Pi 5 throttles without a fan. Get the official Active Cooler or a case with a fan built in.
- Skip the 16GB unless you have a specific reason. At $305 it costs more than a used mini PC that will run circles around it.
Pi 400, Pi 500, and Pi 500+: The Keyboard Computers
These are Pi boards built into a keyboard, meant as desktop computers rather than headless servers. The Pi 400 (4GB) held its $60 price through the memory increases. The newer Pi 500 and Pi 500+ took repeated increases across the 2026 price rounds, with the 500+ carrying more memory and built-in storage; the 500+ has gone from $200 at launch to $410.
For privacy self-hosting, ignore these. You are paying for a keyboard and case you do not need on a box that lives in a closet. They are fine as a cheap Linux desktop, not as a server.
What Actually Matters Besides the Board
The board is half the purchase. The parts around it are where cheap kits and marketplace listings quietly cut corners.
The power supply (do not cheap out)
The single most common Raspberry Pi problem is a bad power supply. Undervoltage shows up as random reboots, USB drives that vanish, SD-card corruption, and throttling that looks like a slow board. On the Pi 5 it is worse: without a compliant 5V/5A supply the board limits USB current to 600mA on purpose. Buy the official 27W USB-C supply, which delivers a stable 5.1V/5A. A generic phone charger is how you spend a weekend debugging a hardware problem that does not exist. The Pi Hut's PSU explainer is a good sanity check.
Cooling
The Pi 5 throttles without a fan under sustained load. Get the official Active Cooler (a heatsink and fan that clips onto the board) or a case that includes a fan. A passive heatsink alone is not enough for a Pi 5 running services around the clock. The Pi 4 is more forgiving but still benefits from a heatsink in an enclosed case.
Storage: SD card, and why counterfeits are everywhere
MicroSD cards are the weak link in any Pi. Two rules:
- Buy a genuine card from a brand you trust. Stick with Samsung or SanDisk, and look for an A2 application-class card for better random I/O. Even then, SanDisk is one of the most counterfeited brands online.
- Avoid the sketchy marketplaces. Counterfeit cards report a fake, inflated capacity and use garbage flash: a "512GB" card might really hold 64GB and corrupt the rest. Skip AliExpress, Temu, Wish, and no-name third-party sellers. When a new card arrives, test it with a free tool like H2testw before you trust it with anything.
NVMe boot: the reliability upgrade
If your Pi 5 is a server you care about, boot it from an NVMe SSD instead of a microSD card. The official Raspberry Pi M.2 HAT+ converts the Pi 5's PCIe connector to a single M.2 slot. It runs a single-lane PCIe 2.0 link at roughly 500MB/s peak and takes 2230 or 2242 drives. Compared to a microSD card, an NVMe drive is 10 to 30 times faster on reads and has far better write endurance, which is the part that actually kills SD cards over months of a database logging every day. With the official HAT+, PCIe activation happens automatically, so you do not have to hand-edit config files. Third-party HATs from vendors like Geekworm and Waveshare exist and work, but the official one is the least-fuss option.
Kits vs Bare Boards, and Who Sells What
A kit bundles the board with a case, cooling, a power supply, a microSD card, and cables. You pay a premium for the convenience and for not having to guess whether the PSU is real. A bare board plus parts you pick yourself is cheaper and lets you avoid the microSD card you would want to replace anyway.
CanaKit
CanaKit is the default kit brand in the US and Canada. A typical Pi 5 Starter Kit includes the board, a 128GB microSD, their Turbine case, a heatsink, a low-noise PWM fan, a USB-C PD power supply, a card reader, and two micro-HDMI cables. Good for someone who wants one box that just works. Test the bundled microSD before trusting it.
Vilros
Vilros is another US kit seller with similar bundles across Pi 4 and Pi 5. Comparable to CanaKit; check the exact contents and the PSU wattage before buying, since kit contents vary between listings.
PiShop.us and Adafruit
PiShop.us is an authorized Raspberry Pi reseller and a good place to buy bare boards, the official Active Cooler, the 27W PSU, and the M.2 HAT+ individually. Adafruit sells boards and a deep catalog of HATs and accessories, with genuinely useful documentation. If you already know what you want, buying the parts a la carte from either beats a kit.
The Pi Hut
The Pi Hut is the go-to UK reseller for boards, accessories, and clear buying guides. Best pick if you are outside North America.
Honest Notes Before You Buy
Our verdict on the platform: 🟢 Trustworthy hardware, gone expensive. The boards are well-supported, the software is clean, and there is no privacy scandal hiding in Raspberry Pi OS. The catch in 2026 is price. On the higher-memory models you are paying enough that a mini PC deserves a look. Buy the Pi for what the Pi is good at, not out of habit.
Raspberry Pi is a public company now. Does it matter?
In June 2024, Raspberry Pi Holdings plc listed on the London Stock Exchange, priced at £2.80 a share, valuing the company around £542 million. The nonprofit Raspberry Pi Foundation remains the main shareholder, and Arm and Sony are strategic shareholders. Being publicly traded means shareholder pressure on margins is now a real force, and the aggressive 2025 to 2026 price increases arrive with that context. Being fair: the stated cause (LPDDR4 memory competing with AI data centers) is a genuine industry-wide squeeze, not an invented excuse. The takeaway is not "the company sold out." It is "the price you remember from a few years ago is gone, so compare against alternatives honestly."
Raspberry Pi OS privacy: no manufactured scandal here
Raspberry Pi OS does not ship hidden telemetry that phones home from a headless server. The one piece of data collection is in the Raspberry Pi Imager (the flashing tool on your desktop), which has an optional, clearly toggle-able usage-statistics feature. Per Raspberry Pi's own policy it records no personal data and no IP address. Raspberry Pi Connect, the browser-based remote-access service, is free, opt-in, and off until you enable it; it uses an encrypted peer-to-peer connection brokered through Foundation servers and opens no inbound ports on your router. Real caveat: because Connect is brokered through Raspberry Pi's servers, it is not fully self-hosted. If that bothers your threat model, use WireGuard and plain SSH instead, which is what most of our guides do anyway. None of this rises to a scandal.
When a used mini PC beats a Pi
This is the uncomfortable part in 2026. Once you are spending Pi 5 8GB or 16GB money ($175 to $305) plus a case, a cooler, a HAT, and an SSD, a used mini PC or a new Intel N100 or N150 box is often the better buy. You get more CPU, x86 compatibility (some containers ship no ARM image), and RAM and storage you can actually upgrade later. For a heavier homelab or a real NAS, the mini PC is the right answer. The Pi still wins on power draw, size, GPIO pins, and the enormous project ecosystem. But do not buy a top-end Pi on autopilot. Our off-site backup pick and the NAS buy vs build guide cover where the line is.
Not Every Job Is a Pi Job
If all you want is a VPN and a firewall at the edge of your network, a purpose-built privacy router is less hassle than a Pi you have to maintain. See our privacy router comparison and the GL.iNet review. A Pi is for when you want to run your own services, not just route traffic.
Where to Buy

The Bottom Line
Buy Small, Add an SSD, Skip the 16GB
Just Pi-hole: a $15 Zero 2 W, a genuine microSD, and a decent power supply. Done.
Pi-hole plus a WireGuard VPN: a used Pi 4 (2GB) for the wired Ethernet port. Cheap and reliable.
A full privacy home server: a Pi 5 (8GB, $175), the official 27W supply, the Active Cooler, and an NVMe SSD on the M.2 HAT+. Boot from the SSD, not the SD card.
Anything heavier, or a real NAS: price out a used mini PC first. In 2026 it usually wins on value, and you can upgrade its RAM and storage later.
