Travel straight back to 1999 and the turn-of-the-millennium golden age of computing with an authentic, rock-solid retro battlestation: an original Gateway 450 (LPMINI-TOWER Model TBR3 450 PII!) Mini-Tower PC running a clean, rock-solid installation of genuine Microsoft Windows 2000 Professional SP4!

Having an authentic, stable Windows 2000 Professional Service Pack 4 installation with full hardware drivers makes this machine exceptionally desirable for vintage computing enthusiasts, collectors, and retro gamers: built on Microsoft's ultra-stable NT 5.0 kernel, Windows 2000 delivers rock-solid crash protection and pure 32-bit execution, while maintaining full compatibility with late-90s and early-2000s DirectX titles, DOS-box software, and classic productivity suites!

Finished in Gateway’s unmistakable late-1990s contoured beige mini-tower chassis featuring lower perforated intake detailing, dual optical drive bays, and the iconic green Gateway emblem, this PC is powered by an authentic Slot 1 Intel Pentium III Processor clocked at 450MHz (Katmai 250nm architecture, 512KB L2 cache, 100MHz Front-Side Bus), an upgraded 192 MB of high-speed SDRAM (196,132 KB recognized), and an internal 40GB Ultra ATA IDE hard drive (37.2 GB formatted NTFS C: partition with over 32 GB of free space).

For retro PC gamers, vintage hardware collectors, and software archivists, a bare-metal 450MHz Pentium III tower equipped with dedicated AGP graphics and dedicated audio is the sweet-spot bridge system: it delivers pure, non-emulated hardware execution for late-1990s through early-2000s classics that suffer from DRM blocks, timing glitches, or audio mapping issues on modern operating systems. Backed by a dedicated AGP graphics card with analog VGA output and a dedicated PCI sound card featuring an authentic 15-pin Gameport / MIDI interface, it is primed and ready to run legendary titles like Half-Life (1998), StarCraft: Brood War, Diablo & Diablo II, Warcraft II: Tides of Darkness, Quake II & Quake III Arena, Unreal & Unreal Tournament (1999), Age of Empires II: The Age of Kings, RollerCoaster Tycoon, Command & Conquer: Tiberian Sun, Fallout 2, SimCity 3000, Deus Ex, and The Curse of Monkey Island!

Condition Notes

• Functional Condition: 100% bench-tested and fully operational. Boots cleanly and swiftly into its installation of Windows 2000 Professional SP4 with all video acceleration and audio controllers verified. The Intel Pentium III 450MHz processor runs cool and responsive, system memory tests healthy to 192MB, and the 40GB IDE hard drive reads and writes cleanly with a healthy NTFS partition structure. All rear ports respond promptly, the CD-ROM drive ejects smoothly and reads media, the floppy drive reads disks, cooling fans spin freely, and the dedicated AGP card outputs a crisp, rock-solid analog video signal.

• Cosmetic Condition: Great vintage condition overall. The classic beige front bezel, side steel casing, and internal chassis are structurally solid with no missing feet or loose panels. Shows light, normal cosmetic surface marks, faint shelf wear, and minor vintage patina/aging on the beige exterior consistent with late-90s age. Please note: As visible in photos IMG_9470 and IMG_9471, there is a fine hairline plastic stress crack on the front bezel directly below the drive bay cutout above the power button; this is purely cosmetic and does not affect chassis stability or operation. Original front badges, green Gateway cow-box emblem, and rear manufacturing barcode label (Serial No: 0014643937) remain intact and legible. Please review the high-resolution photos for an exact look at physical condition.
