Build a quiet gaming PC from Dell Precision T5810 with e5-1650

Want a gaming PC that looks like something out of a sci-fi movie lab but costs a fraction of the price of a new one? Here's a complete guide on how to build a stylish and quiet "RGB Edition" from a Dell Precision T5810 workstation - with real photos for inspiration, upgrade suggestions , and approximate prices in CZK .

Starter package (barebone): 2× Xeon v5 , 32 GB RAM , 256 GB NVMe PCIe – 2,490 CZK .
Note: The T5810 is a single-socket platform (LGA2011-3, Xeon E5 v3/v4). If you really want 2 CPUs, go for the T7810/T7910 or the older T7610. Below I will calculate the T5810 and recommend the ideal single-CPU for gaming.

What the T5810 can do and why it's great for gaming

• Massive chassis with well-thought-out airflow and quiet operation.

• The 685 W/825 W power supply can handle even more powerful GPUs (without tinkering).

• PCIe 3.0 x16 slots for graphics + additional slots for NVMe adapters.

• ECC DDR4 RDIMM – stability, 32–128 GB as needed.

Gaming CPU Tip: The best gaming results are achieved with the Xeon E5-1650 v3 (6C/12T, 3.5–3.8 GHz) or E5-1660 v3/v4 , as they have high clock speeds . Multi-core 12–14-core chips (e.g. E5-2680 v4) are great for multitasking, but tend to be slower in games due to lower frequencies.

Three ready-made upgrade packages (with prices)

Prices are approximate second-hand / reconditioned (Q3–Q4 2025) so you can make a budget. I take the barebone price of 2,490 CZK as a basis and add upgrades.

1) Budget Gamer (~10–12 thousand CZK total)

• CPU: keep what you have, or E5-1650 v3 … 900 CZK

• GPU: GTX 1660 Super 6GB … 3,000 CZK

• RAM: 32 GB ECC (base) … 0 CZK

• Disk: add SATA SSD 1 TB (games) … 1,200 CZK

• NVMe adapter (if missing): PCIe×4 … 200 CZK

• Wi-Fi 6 + BT card (M.2/PCIe with bracket): 600 CZK

• RGB and side panels (acrylic, LED strip, magnets): 500 CZK

• Base + upgrades: 2,490 + 900 + 3,000 + 1,200 + 200 + 600 + 500 ≈ 8,890 CZK

  • possible gaming keyboard/mouse/headset (+1–3 thousand CZK)

Expected performance (1080p, medium-high): Fortnite, Valorant 120–200 FPS; Forza/AC Valhalla 55–75 FPS; Cyberpunk 2077 ~45–60 FPS (without RT).

2) Sweet-Spot 1440p (~15–20 thousand CZK total) – recommended

• CPU: E5-1660 v3/v4 … 1,500–2,500 CZK

• GPU: RTX 3060 12 GB … 5,500 CZK , or RTX 2070 Super … 5,000 CZK

• RAM: 32–64 GB ECC … 0–1,200 CZK (depending on addition)

• Disks: NVMe 1 TB (OS+2–3 games) … 1,500 CZK + SATA SSD 2 TB (library) … 2,000 CZK

• Wi-Fi 6E card: 900 CZK

• RGB/acrylic accessories + quiet 120 mm PWM fan: 800 CZK

Budget with RTX 3060: 2,490 + 2,000 + 5,500 + 1,500 + 2,000 + 900 + 800 ≈ 15,190 CZK
Performance (1440p, high): most AAA 60–90 FPS; eSports games 144+ FPS.

3) High-End for 144 Hz/ultra (~25–35 thousand CZK total)

• CPU: E5-1660 v4 (or 1680 v3) … 2,500–3,500 CZK

• GPU: RTX 3070 / 3070 Ti … 7,500–9,000 CZK , or RTX 3080 10 GB … 10,000–12,000 CZK

• RAM: 64 GB ECC … 1,200–1,800 CZK

• Disks: NVMe 2 TB 3,000 CZK + SATA SSD 2–4 TB 2–4 thousand CZK

• Silent cooling + new pastes/dust: 700 CZK

• ARGB control (hub + remote): 600 CZK

Performance (1440p ultra / 4K medium): 3070 ≈ 80–120 FPS at 1440p; 3080 handles 4K 60+ FPS on most non-RT titles.

Practical steps – from “office tank” to gaming jewel

1. Update BIOS (latest version for T5810) and reset CMOS.

2. CPU : if you're aiming for FPS, swap for an E5-1650/1660 (v3/v4) .
   – Apply new paste , blow through the radiator, check the assembly screws.

3. Graphics card :
   – Fits up to three slots (check length ~28–30 cm).
   – Connect the 8-pin/2×8-pin power supply directly from the Dell power supply (it has the appropriate branches).

4. Discs :
   – NVMe via PCIe adapter as system disk (fast boot).
   – SATA SSD for a large game library.

5. RAM : keep 32 GB ECC RDIMM , possibly expand to 64 GB .

6. Silence and airflow :
   – Replace the rear 92/120 mm fan with a PWM silent one ; clean the dust filters.
   – VO/S set the “Balanced” power plan; you can fine-tune the GPU fan curve in MSI Afterburner.

7. Style :
   – Acrylic side panel (cut 3–4 mm plexiglass, attach magnets/screws).
   – Power LED strips (5V ARGB) from SATA; use cable channels for cleanliness.
   – Shoot a short RGB video after dark – it looks 10x better 😉.

Frequently asked questions

• "Will the power supply power the RTX 3080?" Yes, the 825 W variant is no problem; at 685 W, keep the GPU undervolted (Afterburner -60 to -120 mV), the real consumption will go down and so will the noise.

• “Can it be moved into a gaming case?” Yes, but the Dell has good airflow and a rigid chassis; plus, you save money.

• "Ray Tracing?" Take an RTX 3070/3080 and turn on DLSS/FSR .

Mini-checklist before playing for the first time

• ✅ BIOS OK, RAM detected, NVMe boots

• ✅ GPU keeps ~60-75 °C, CPU up to ~75-80 °C (stress/benchmark)

• ✅ Installed drivers (GPU, Wi-Fi/BT, Dell chipset)

• ✅ Afterburner: fan curve + possible undervolt

• ✅ Windows Game Mode + HAGS ON (with RTX), unnecessary auto-starts disabled

Summary

• The T5810 is the perfect foundation for a cheap, nice, and quiet gaming build.

• With E5-1650/1660 and RTX 3060/3070 you get beautiful 1440p with high FPS.

• Acrylic + RGB turns the workstation into a "showcase" - see photos above.

• The whole thing will cost around 10,000-20,000 CZK depending on the GPU you choose – a fraction of a new gaming setup.
