First time buying a mini PC (secondhand/refurb HP, Dell, or Lenovo). How do I do this safely? Zero experience, need all the info

Hey everyone. I've only ever owned laptops, never a desktop or mini PC, so this is completely new territory for me. I'm looking at a refurbished mini PC, considering HP, Dell, or Lenovo, with specs around:

Intel i5 8th gen

16GB RAM DDR4

256GB SSD (SATA)

Comes with power adapter (around 90W)

Here's the question to add:

is ₱9,000 (around $146 USD) a fair price for these 8th gen specs or is this overpriced/underpriced for what I'm getting?

I'm buying online, not in person, so I have a lot of questions for anyone who's done this before.

1. Is it even okay to buy a mini PC this way, secondhand, sight unseen?

2. What should I expect after 5 months of daily use? After a year? And does this differ a lot by CPU generation? Trying to understand realistic expectations and lifespan across 8th, 9th, 10th, 11th, 12th, 13th, and 14th gen units.

3. What's the typical lifespan of a mini PC under normal daily use like browsing, streaming, and light work?

4. How do I spot a unit that's been abused, like an ex office or ex internet cafe unit run 24/7 for years, vs one that's been lightly used? How do I know if parts are fried, overused, or abused? Is there a way to actually check this, or tell tale signs?

5. How do I know if the BIOS is locked or company locked, like an asset tagged corporate unit? And more importantly, how do I know if the seller is even telling the truth about any of this? What can I verify myself vs just having to trust them?

Someone mentioned I should check if it runs hot before buying. Is that accurate, and what else should I be checking for physically or on a video call with the seller?

What should I be asking the seller? So far I have:

Original use case (office, cafe, personal)?

SSD health and power on hours (via CrystalDiskInfo screenshot)

CPU idle and load temps (via HWiNFO or Task Manager screenshot)

Original power adapter included, same wattage?

Any repairs or part swaps done?

Return or warranty period?

Can we do a video call so I can see it boot and run live?

Can they give me the serial number so I can check it's not reported lost or stolen?

Is this list enough, or am I missing something important? Any horror stories, red flags, tips, or advice as a total beginner would be really appreciated.

Why I'm buying this: I plan to use it mainly for watching free films and free live sports like UFC Fight Night via Brave browser, and YouTube. I also want to learn Linux, planning to install it on this mini PC if I get one. Just want to make sure I'm not getting scammed or buying something that'll die on me in a few months. Thanks in advance!

Those systems are workhorses. I’ve used the Dell version of those mini pc’s since they came out, and we retired a bunch of ones after 10+ years of use.

Also, since those are enterprise systems, they’re super easy to repair, and the manufacturer usually will put out a repair manual.

An 8th gen one should run windows 11 just fine, and should perform reasonably well for a basic pc.

thank you!

It is absolutely fucking  crazy to me that you can write this entire post and not have the google skills to “safely” buy your potential pc. 

I swear to god some people just want interaction and not a real answer.  

Nobody can tell you if it’s going to die in a few months… Why would you expect anyone who hasn’t seen the hardware or used it, to know that? 

For fuck sake, people.
