Common Mistakes to Avoid
Learn from others' mistakes when building a deep learning desktop.
Underestimating VRAM needs
Impact: Cannot train larger models, constant OOM errors
Solution: Get minimum 16GB VRAM, prefer 24GB for flexibility
Insufficient cooling
Impact: Thermal throttling, reduced lifespan, noise
Solution: Quality case with good airflow, consider water cooling
Weak PSU
Impact: System instability, crashes during training
Solution: Get 20-30% more wattage than calculated need
Slow storage
Impact: Data loading bottlenecks, wasted GPU time
Solution: NVMe SSD for datasets, fast enough for most workloads
Too little RAM
Impact: Cannot preload data, CPU bottlenecks
Solution: Minimum 32GB, 64GB+ for large datasets
Single GPU tunnel vision
Impact: Limited to single GPU VRAM
Solution: Consider motherboard with multi-GPU support for future
When to Choose Cloud Instead
Sometimes cloud GPUs make more sense than building a desktop.

Choose Cloud When:

  • Need more than 24GB VRAM
  • Training less than 100 hours/month
  • Want to avoid upfront investment
  • Need multiple GPUs occasionally
  • Working with very large models (70B+)

Choose Desktop When:

  • Training 150+ hours/month
  • 24GB VRAM is sufficient
  • Need instant access anytime
  • Strict data privacy requirements
  • Also use it for gaming/other work
