This is a build guide for the quintessential 1999 LAN rig: a Pentium III 600 paired with a Voodoo3 3000, assembled in 2026 for around $400 and tuned for the two games that defined the era's LAN scene — Quake III Arena and Unreal Tournament. The Voodoo3's Glide rendering and the PIII's clean 100 MHz-bus performance deliver exactly the locked, smooth experience these games were built for, and both still have active community servers in 2026. Here's the parts list, the assembly notes that matter, and what to expect when you fire it up.

The target configuration
| Component | Pick | Notes |
|---|---|---|
| CPU | Pentium III 600 (Coppermine/Katmai) | 100 MHz FSB, cool and overclock-friendly |
| Motherboard | Intel 440BX (ASUS P3B-F, Abit BE6-II) | The legendary BX chipset; AGP 2x |
| GPU | Voodoo3 3000 AGP (16 MB) | Glide; the LAN-era rendering standard |
| RAM | 256 MB PC133 SDRAM | Plenty for Win98 SE and era games |
| Sound | Sound Blaster Live! or Audigy 2 ZS | Hardware audio for positional cues |
| Storage | CompactFlash-to-IDE | Silent, reliable, no spinning rust |
| OS | Windows 98 SE | The definitive driver and game target |
Budget around $400 total if you're patient — the Voodoo3 and a clean BX board are the big-ticket items; the CPU and RAM are cheap.
Assembly notes that actually matter
The build is straightforward, but three things determine whether it's reliable. Inspect the 440BX board for bulging or leaking capacitors and recap if needed — 25-year-old electrolytics are the most common failure. Use a CompactFlash-to-IDE adapter instead of a period hard drive: it's silent, immune to mechanical failure, and sidesteps old IDE drive death. And don't trust a two-decade-old PSU with fresh parts — a modern unit with the right connectors is the one sensible anachronism. Set the FSB to 100 MHz, give the PIII a quality period cooler, and seat the Voodoo3 firmly in the AGP slot with the bracket screwed down.
Drivers and tuning
Install Windows 98 SE clean, then apply the unofficial Service Pack plus the USB and storage updates before anything else — they remove most of the rough edges. For the Voodoo3, the final 3dfx reference drivers are the baseline; the community FastVoodoo and Amigamerlin packs add stability and resolution options. Install the Sound Blaster drivers next, enable DirectX hardware acceleration, and finish with DirectX 9.0c, which still supports Win98 and covers everything you'll run. Confirm Glide is present with a quick test before installing games.
What to expect: Quake III and UT99
This is the payoff, and the Voodoo3 3000 delivers exactly what the era promised. At 1024×768 with Glide, both Quake III Arena and Unreal Tournament run at the smooth, locked framerate they were designed around — fluid enough for competitive LAN play, with the distinctive period look that Glide rendering gives Q3 and UT. The PIII 600 keeps the engine fed in botmatches and crowded servers without the hitching that plagued lesser period CPUs. It won't push the triple-digit refresh of a modern rig, but it nails the authentic 1999 feel that's the entire point of the build.
They're still online in 2026
A period rig isn't just a display piece. Quake III Arena lives on through ioquake3 and OpenArena with active public servers, and Unreal Tournament's community keeps masterservers running via the OldUnreal patches. Counter-Strike 1.6 and Half-Life deathmatch are still populated too. Patch your installs to the community-maintained versions, point them at a live server, and you can frag strangers on the same box you'd have hauled to a 1999 BYOC party.
Period peripherals to finish it
A Microsoft IntelliMouse Optical or a period ball mouse, a Model M or era membrane keyboard, and — above all — a CRT complete the build. The CRT's motion clarity and zero input lag are a big part of why period games feel right; pair it with the hardware sound card's EAX cues and you've recreated the full sensory experience, not just the parts list.
Sourcing tips and what to avoid
Patience saves real money on this build. The Voodoo3 3000 and a clean 440BX board are where prices spike, so watch listings and buy the board and CPU as a tested, POSTing combo when you can — it eliminates the most common failure mode, a dead BX board with blown capacitors. Avoid Voodoo3 cards with recapped-but-still-leaking boards, missing AGP brackets, or sketchy "untested" listings at premium prices. PC133 RAM and CF storage are nearly free, so don't overpay there. If a seller shows the rig POSTing into a BIOS screen, you've sidestepped 90% of the risk.
A note on overclocking
The Pentium III 600 has headroom, and period builders loved nudging the FSB, but for a reliable LAN box, leave it at spec. A stable rig that runs all weekend beats a marginally faster one that crashes mid-match, and the Voodoo3 is the limiting factor for these games anyway, not the CPU. If you do experiment, do it after the build is proven stable at stock, and keep the cooler quality high.
Frequently asked questions
How much does a period-correct Voodoo3 + Pentium III LAN rig cost in 2026? Roughly $400 if you're patient on eBay, with the Voodoo3 3000 and a clean 440BX board being the major costs. The CPU, RAM, and CF storage are inexpensive.
How do Quake III and UT99 run on a Voodoo3 3000? Smoothly and at a locked framerate at 1024×768 with Glide — fluid for competitive play, with the authentic period look. The Pentium III 600 keeps the engine fed in busy botmatches and servers.
Can I still play these games online? Yes. Quake III (ioquake3/OpenArena), Unreal Tournament (OldUnreal patches), and CS 1.6 all have active community servers in 2026.
