HP ProDesk 400 G1 SFF — Quad-Core i7 Barebones Desktop (No OS)

A compact HP ProDesk 400 G1 small-form-factor desktop with a quad-core Intel Core i7-4770, 4GB DDR3 and a 1TB hard drive, supplied without an operating system — a clean, ready-to-build base for your own OS install. Professionally tested and backed by a 12-month Reboot IT warranty.

• Quad-Core Intel Core i7-4770: Four cores with Hyper-Threading (3.4GHz, Turbo to 3.9GHz) — genuinely capable performance for office, admin and light multitasking.
• Dual-Display Ready: DVI and VGA outputs drive two monitors for a proper multi-screen productivity setup.
• 1TB Storage + DVD Burner: A roomy 1TB hard drive for files, plus a SuperMulti DVD writer for optical media.
• Your Build, Your OS: Ships with no operating system — install Windows or a lightweight Linux distribution and you have a fresh, bloat-free machine.
• Plenty of Ports: Two USB 3.0, six USB 2.0 and Gigabit Ethernet for all your peripherals.
• Compact SFF Design: A small footprint that tucks neatly onto or under a desk, ideal for offices tight on space.

Performance in Use

The ProDesk 400 G1 is best thought of as a value business workstation and project base. It ships without a storage OS installed, which makes it ideal for IT teams that image their own builds, tinkerers, or anyone wanting a cheap, dependable box for a specific job. Fit your preferred operating system and it's ready for everyday office duties.

With the quad-core i7-4770 and 4GB of RAM, the 400 G1 comfortably handles web browsing, email, word processing and spreadsheets. It is a strong candidate for a lightweight Linux install, which runs briskly on this hardware, or an older Windows build for line-of-business applications. Adding an SSD (in place of or alongside the 1TB drive) transforms responsiveness for very little cost.

The DVI and VGA outputs let you run a comfortable dual-screen setup. Paired with the Gigabit Ethernet and generous USB provision, the 400 G1 makes a capable reception, back-office, workshop or point-of-sale machine. Given its age, it is not intended for modern gaming or heavy creative workloads — think honest, low-cost business computing.

Frequently Asked Questions

Does it come with Windows installed?

No — this unit ships with no operating system. Once you're ready, install Windows or a lightweight Linux distribution of your choice.

Can I add an SSD?

Yes — the 400 G1 has SATA connectivity and drive bays, so you can fit an SSD alongside or in place of the 1TB HDD. An SSD dramatically improves boot and load times.

How many monitors can it run?

Two — via the DVI and VGA outputs.

Will this CPU run Windows 11?

No — the 4th Gen Core i7-4770 is not on Microsoft's Windows 11 support list. Windows 10 or a Linux distribution are the practical choices.

Is a keyboard and mouse included?

A power cord is included. Peripheral inclusion can vary — please contact us if you need to confirm before purchase.

What are the shipping options?

Shipping costs apply based on size and destination — rates are calculated at checkout.
