Travel straight back to 2003 and the absolute golden era of early-2000s desktop computing with an authentic, wonderfully preserved battlestation: an original Dell Dimension 2400 Mid-Tower PC running its factory-original Windows XP Professional installation!

Having the original factory operating system installation makes this system exceptionally desirable for collectors, archivists, and retro enthusiasts: all proprietary Dell Intel 845GV chipset drivers, integrated display drivers, Realtek/ADI audio codecs, and system communication controllers are completely native and fully configured out of the box—with zero missing driver yellow exclamation marks!

Finished in Dell’s celebrated two-tone midnight-gray and charcoal mid-tower chassis featuring the center power medallion with split activity indicator lines, lower curved front intake, and prominent chrome Dell emblem, the Dimension 2400 was one of the most reliable home workhorses of the XP generation. Powered by an authentic Socket 478 Intel Pentium 4 processor clocked at 2.40GHz (Northwood 130nm architecture, 512KB L2 cache, 400MHz/533MHz FSB), 512MB of DDR SDRAM, and an internal 40GB Ultra ATA IDE hard drive (37.2 GB formatted NTFS C: partition with over 19.7 GB of free space), this tower boots cleanly and swiftly into an authentic installation of Microsoft Windows XP Professional (Version 2002, Service Pack 3)!

For retro PC gamers, vintage hardware collectors, and software archivists, an authentic bare-metal Windows XP machine is the ultimate platform for late-90s through mid-2000s PC classics that run into severe DRM blocks (SafeDisc/SecuROM), 16-bit installer bugs, scaling issues, or audio driver incompatibilities on Windows 10/11. Backed by integrated Intel Extreme Graphics, it effortlessly powers through era classics like The Sims & The Sims 2, Diablo II: Lord of Destruction, RollerCoaster Tycoon 1 & 2, Half-Life & Counter-Strike, Warcraft III: Reign of Chaos, StarCraft: Brood War, Age of Empires II, Civilization III, Fallout 1 & 2, Heroes of Might and Magic III, and classic PopCap games.

Built with an expansive drive array and authentic legacy hardware ports:

• Dual 5.25" optical drives: an upper DVD-ROM reader and a lower secondary DVD-ROM drive (ideal for simultaneous disc operation and reading)

• An integrated 3.5" 1.44MB floppy diskette drive (essential for vintage floppy gaming, DOS boot disks, and retro diskette archiving)

• Front-facing convenience panel recessed in the lower chin featuring dual USB 2.0 ports and a 3.5mm headphone jack

• Full motherboard rear legacy I/O: dual PS/2 ports for vintage mechanical keyboards and ball mice, a 9-pin RS-232 serial COM port, and a full DB-25 parallel printer port

• 4 rear high-speed USB 2.0 ports, 10/100 Ethernet networking, and 3.5mm color-coded analog audio jacks

• Open internal PCI expansion slots ready for a dedicated vintage PCI graphics card or Sound Blaster audio card

Condition Notes

• Functional Condition: 100% bench-tested and fully operational. Boots cleanly and swiftly into its original factory installation of Windows XP Professional SP3 with all native Dell drivers and system utilities verified. The Intel Pentium 4 2.40GHz processor runs cool and responsive, memory tests healthy, and the 40GB IDE hard drive reads and writes cleanly with a healthy NTFS partition. The 3.5" floppy drive reads media properly, both DVD-ROM optical drives eject and read media smoothly, cooling fans spin freely, and the onboard VGA port outputs a crisp, rock-solid display signal.

• Cosmetic Condition: Great vintage collector condition overall. The two-tone dark gray front bezel, central medallion, and heavy steel side panels are structurally solid with no broken covers, missing feet, or cracked plastic. Shows light, normal cosmetic surface marks, faint shelf wear, and minor hairline scuffs consistent with careful home/office use and vintage age. Original front badges, embossed Dell logo, rear service tag barcode label (8SJT731), and motherboard part sticker remain intact and fully legible. Please review the high-resolution photos for an exact look at physical condition.
