Pre-built vs custom PC. — The South African reality, line by line.

Component transparency — what's actually inside the box

The single biggest difference between an Evetech custom build and a grey-market prebuilt is how much you know about the parts before delivery. A custom build spec sheet names the exact SKU of every component; a prebuilt spec sheet names categories.

Why this matters in SA specifically: the "RTX 5070" line on the right could ship as a Palit Dual (entry AIB partner, narrower cooler, 2-slot) instead of the 3-fan Gigabyte Gaming OC pictured on the marketing page. Both are real RTX 5070s. The Palit will thermal-throttle 4-6°C earlier under sustained load and arrive 70-100MHz lower on boost clock — performance you paid for that you'll never see.

The same swap plays out on PSU more dangerously. A "850W gaming PSU" can be a no-name unit that cost R350 wholesale rebranded with RGB stickers. Under sustained load it can deliver 720W stable and trip safety on transient spikes — exactly the kind of failure that destroys components and arrives just outside the 1-year prebuilt warranty.

Warranty bundling — the bit that hurts in year two

Every component in a PC has a manufacturer warranty — typically 2-3 years for GPUs, 5 years for premium SSDs and PSUs, 3 years for motherboards. With a custom build these warranties stay with you in full. With a grey-market prebuilt, you discover something painful in year two.

The grey-market warranty problem: the system integrator buys components in bulk months before assembly. By the time the PC ships to you, the 2-year GPU warranty has already started — sometimes 4-8 months ago. When the card dies in month 22 of your ownership, the manufacturer warranty has already expired.

With Evetech, every component goes through serial-number registration at point of assembly. You get the full warranty period from your delivery date, with original RMA paths to each manufacturer through Evetech as the registered SA partner.

The QA burn-in advantage

A new PC has the highest failure probability in its first 72 hours of operation. Marginal RAM, cooler mounting issues, DOA GPUs and unstable BIOS settings will surface inside the first few stress cycles. The question is whether they surface in the shop or in your living room.

Evetech QA burn-in includes:

• Prime95 small-FFTs (CPU stress) for 4+ hours, verifying no thermal throttling and stable voltages.
• FurMark + Heaven loop (GPU stress) for 4+ hours, verifying cooler contact and VRAM stability.
• MemTest86 four full passes overnight, surfacing marginal RAM kits before delivery.
• Full benchmark loop (Cinebench, 3DMark, CrystalDiskMark) for performance baseline against expected scores.
• Visual inspection — cable management, fan direction, RGB headers, thermal paste spread verification on cooler remount.

Grey-market prebuilts often skip this. The PC ships within 24 hours of assembly, with a 5-minute "did it POST?" check. The PC reaches you, runs Windows install fine, and then crashes in week three under your first multiplayer session.

Build time vs ship time — the real timeline

Prebuilts win speed by 1-3 days. Custom builds win by 1-3 days on stability. Here's how the actual SA timelines compare.

The 2-3 days you save with grey-market is the same 2-3 days you'll spend troubleshooting an unstable XMP profile, reseating a cooler with bad paste spread, or RMA-ing a DOA GPU through a SA importer who insists "the box warranty doesn't cover that".

Customisation depth — when it actually matters

Most buyers think they want full customisation. In practice, 80% of buyers fit one of 15 popular configurations. Customisation only matters when your needs sit outside the common path.

When custom is necessary:

• Specific case — ITX builds, ultra-quiet cases, premium showcases (Lian Li O11, Fractal North) that no prebuilt offers.
• Workstation specs — Threadripper, multiple NVMe, ECC RAM, dual GPU rigs that prebuilts don't carry.
• Specific aesthetics — colour-matched RGB, custom loop water cooling, vertical GPU mount.
• Component carry-over — reusing your existing GPU, SSD or PSU into a new platform.
• Quiet builds — Noctua-based, low-RPM tuned for office or studio use.

When pre-configured is plenty: 1080p / 1440p gaming, content creation on standard ATX, mainstream Ryzen 7 / Core Ultra 7 builds with off-the-shelf cases. The pre-configured spec gets you to "playing" two days faster with identical reliability.

The SA used market reality for prebuilts

If you sell your PC in 2-4 years on Carbonite, Gumtree or PC enthusiast Facebook groups, the transparency of a custom build pays back a second time. Buyers in SA's used market have learned the prebuilt risk and discount accordingly.

The custom build sells for R3,000-R4,500 more on resale despite costing less new. Three years of compounding favour the buyer who chose transparency on day one.

When each path wins

Common prebuilt traps to spot before buying

DDR5 listed without speed. A "32GB DDR5" line that doesn't specify 5600/6000/6400 is almost certainly the slowest available. Real performance loss: 4-9% in CPU-bound gaming.

NVMe listed without generation. "1TB NVMe SSD" can be Gen3 SATA-interface NVMe (1,800MB/s) instead of Gen4 (7,000MB/s). The difference is 3-4x in load times and is barely visible on the marketing page.

Motherboard model hidden. "B650 motherboard" can be an entry SKU with 8-phase VRM that throttles a Ryzen 9 7950X under sustained load. Always demand the specific motherboard SKU.

Cooler downgrade. "Liquid cooler" can be a 120mm AIO instead of the 240mm or 280mm needed for the CPU. Result: 8-15°C higher CPU temps under load.

Case fan count. A case rated for 6 fans often ships with 2 in grey-market prebuilts. The system runs hot and noisy from day one.

Key takeaways

1. Component transparency is the biggest gap — custom builds list every SKU, prebuilts list categories.
2. Warranty bundling matters in year two — custom builds preserve full manufacturer warranties from delivery date.
3. 24-hour QA burn-in catches 1 in 80 RAM and 1 in 200 PSU failures before they reach you.
4. Custom builds resell for R3,000-R4,500 more in SA's used market — transparency premium compounds.
5. Pre-configured beats custom only when you need same-week delivery on a mainstream spec.
