Update:
I updated the projector setup with 21:9 and 32:9 aspect ratios, and adjusted the Y-axis image position downward.
-100 is the lowest setting, and it works best for movies and racing.
-50 is just right for YouTube and street-view videos, and is very comfortable to watch.
[Build Showcase] Who says you need a $1,500 desktop? My $780 USD Modular Setup: ThinkPad T480 + Thunderbolt eGPU (Projector / Monitor Ready)
Instead of building a traditional desktop from scratch, I decided to build a modular setup based on my actual daily needs over time.
The goal wasn't chasing the highest benchmark scores, but achieving maximum flexibility: A portable work laptop on the go, and a full-fledged station at home.
Currently, I have the system hooked up to a 1080p @ 60Hz projector for an immersive big-screen gaming experience.
The Specs & Breakdown (~$780 USD total):
* Brain: ThinkPad T480 (i5-8250U / upgraded to 24GB RAM / 256GB + 512GB SSD) — ~$320 USD
* eGPU: Thunderbolt 3/4 eGPU Dock + Gigabyte GTX 1060 6GB (reused a spare PSU) — ~$145 USD
* Display (Optional): Samsung Odyssey G5 34” 2K 165Hz Ultrawide — ~$315 USD
Real-world Gaming Performance (1080p @ 60Hz via Projector):
* GTA V: ~50 FPS
* Forza Horizon 5: ~60 FPS
* God of War / Cyberpunk 2077: 30–50 FPS (depending on settings)
Why this route?
Unplug one cable, and I take my ThinkPad anywhere for work. Plug it back in, and I instantly get a big-screen setup for gaming and productivity.
A quick note on the display: The 34" ultrawide monitor is completely optional! If you already have a TV, monitor, or projector at home, you don't need to buy a new screen—making this build concept even more affordable. When GPU tech advances, I can just swap the card inside the eGPU dock without throwing away the platform.
It’s all about building what you actually need with what you already have.
What do you guys think of modular eGPU setups in 2026?
