# What Is a Modular Laptop, and Is One Worth Buying?

> A modular laptop lets you choose and swap its parts. What you can change, what you give up, who benefits and how to decide if one suits you.

**In short:** A modular laptop is built from parts you can choose and later replace: memory, storage, screen, keyboard, ports and even the mainboard. It is worth it if you keep laptops for years or want specific ports, and less so if you want the thinnest machine possible.

A modular laptop is built from parts you choose and can replace later: the mainboard, memory, storage, screen, keyboard and the ports on the side. Most laptops are sealed units where a failed part means a failed laptop. A modular one is closer to a small desktop in a portable shape.

## What you can choose

In our [builder](/build) you pick each of these separately:

- **Chassis.** The body, in 13.5, 14 or 16 inch sizes.
- **Mainboard.** The processor and the board it sits on.
- **Memory.** One module or a pair, in the type your board takes.
- **Storage.** One or more drives, depending on how many slots the board has.
- **Screen and keyboard.** Matched to the chassis you picked.
- **Expansion cards.** The ports: USB-C, USB-A, HDMI, DisplayPort, a microSD reader, Ethernet and a headphone jack, in as many bays as the chassis has.
- **Charger and operating system.**

Only the 16 inch chassis has a bay for the optional graphics module.

## What you can change later

Memory and storage can be swapped for larger ones when you need them. A cracked screen or a worn keyboard can be replaced on its own. When a newer mainboard that fits your chassis is available, you can upgrade the brain of the laptop and keep the rest. And if you need a different port today, you swap an expansion card instead of buying a dongle.

## Why people choose one

- **Repair instead of replace.** A part fails and you replace that part.
- **The ports you actually use.** Four USB-C, or two plus a card reader. You decide.
- **A longer life.** The parts that age fastest are the ones you can change.
- **Less waste.** Fewer whole laptops end up discarded for one broken component.

## What you give up

Honesty matters here, because a modular laptop is not the right answer for everyone.

- **A little thickness and weight.** Replaceable parts need room and connectors, so the thinnest ultrabooks are still thinner.
- **A price premium on some specs.** Mass-market laptops are made in huge volumes, and the same headline specs can cost less in a sealed design.
- **Fewer one-click choices.** You make more decisions. The builder checks compatibility for you, but you are still choosing.

## Who it suits

A modular laptop is a good fit if you keep laptops for years, like to repair or upgrade, need a particular mix of ports, or just want to pick the parts instead of accepting a bundle. It is a poor fit if you want the thinnest and lightest machine, or if you will never open the lid beyond using it.

## How we handle the hard part

The risk with any custom build is picking parts that do not work together. The builder prevents that: it only offers parts that fit the ones you chose, explains why when something does not, and checks the whole configuration again at checkout. Then a person on our team assembles the laptop, installs the operating system and runs burn-in tests before it ships, so it arrives ready to use. Or, if you would rather put it together yourself, it ships as a [DIY kit](/guides/diy-laptop-kit-or-assembled) without the assembly fee.

## How to decide

Ask yourself three questions. Will I still be using this laptop in four or five years? Do I care which ports it has? Would I rather replace one part than the whole machine? If the answer to two of them is yes, a modular laptop is worth a look.
