Mini-PC

What is this?

A mini-PC is a small desktop computer - about the size of a thick book or small lunch box. Popular brands include Intel NUC, Mac Mini, and various business mini-PCs from Dell, HP, or Lenovo.

They're like regular desktop computers but shrunk down, using less power and making less noise. They use regular laptop parts inside.

Who is this for?

Perfect for:

• Small businesses running their first system
• Websites with 100-500 visitors per day
• Running business tools (like inventory systems or booking software)
• Home labs where you're learning IT or testing ideas
• Replacing 2-3 single board computers that are getting messy

Not ideal for:

• Services with thousands of users at once
• Storing huge amounts of video
• Running many different applications at the same time
• Critical services where any downtime costs money

What can break?

Common problems:

• Hard drive failure: The internal drive can fail after 3-5 years (budget $50-150 to replace)
• Power supply: The small power brick can fail ($30-60 to replace)
• Fan noise: The cooling fan can get loud or fail ($20 part, but fiddly to replace)
• Network issues: If your router fails or internet goes down, so does your service

Cost to fix: Usually $100-300 for common repairs

How long they last: 5-7 years with proper care before major components need replacing

How to maintain it

Weekly (2 minutes):

• Check that it's responding
• Glance at disk space (keep at least 20% free)

Monthly (15 minutes):

• Update software
• Check backup is working
• Clean dust from vents with compressed air

Every 6 months (30 minutes):

• Full system backup
• Check disk health (use built-in tools)
• Review what's running and remove unused programs

Every 2-3 years:

• Consider replacing internal drive before it fails
• Reapply thermal paste to CPU (or pay someone $50)

When to level up

Move to a Tower/Rack when:

• You need to run 5+ different services
• You need more storage than 2TB
• Multiple people depend on it being up 99.9% of the time
• You want redundant drives (RAID) so one can fail without losing data

Move to Cloud Hosting when:

• You have users across multiple continents who need fast access
• Your traffic is unpredictable (spikes and valleys)
• You don't want to be responsible for hardware maintenance
• Downtime costs you more than $200/hour in lost business

Quick checklist

Before buying ($300-800 new, $150-400 refurbished):

• [ ] At least 8GB RAM (16GB if running database)
• [ ] SSD storage (faster and more reliable than HDD)
• [ ] Gigabit ethernet port (not just WiFi)
• [ ] At least 2 USB ports for accessories
• [ ] Check noise levels if it will be in your workspace

Setup essentials:

• [ ] Uninterruptible Power Supply (UPS) - $80-150
• [ ] Quality ethernet cable (Cat6) - $15
• [ ] External USB backup drive - $80
• [ ] Mounting bracket if tucking it under desk - $20
• [ ] Temperature monitoring software

Monthly monitoring:

• [ ] CPU usage (should average under 60%)
• [ ] RAM usage (should have 2GB free minimum)
• [ ] Disk space (keep 20% free)
• [ ] Temperature (should stay under 80°C / 176°F)
• [ ] Backup completed successfully

Real-world example

Mike's online shop:

• Traffic: 200 orders per day
• Services: Website + inventory system + email
• Hardware: $450 refurbished HP mini-PC
• Cost: $45/month (electricity + internet + backup storage)
• Uptime: 99.2% (went down twice during power outages)
• His verdict: "Way more reliable than the Raspberry Pi I started with. Paid for itself in 3 months compared to cloud hosting."

Noise & Heat

Noise level: Quiet - about the same as a laptop fan. You can work in the same room comfortably.

Heat output: Warm but not hot - about the same as a laptop. Don't put it in a closed cabinet without ventilation.

Power usage: 15-45 watts typical (about the same as a light bulb)
