You’re giving two very mixed signals here.

“Old Pentium,” as someone else said, can mean anything back to 1993, but “4 TB drive” suggests something far newer than that.

I ask because that affects the expected energy draw of the server.  If it’s old, it could be 200 W or so.  If you’re using “old” rather loosely, then it could be down in the double digits.

Here’s why it matters:


At 12 pence per kWh — typical for power in some places in your country, based on your TLD — it’s going to cost you about 1 pound per watt consumed if it runs all day every day.  If it draws 35 W, that’s £35/yr.  If it draws 200 W, that’s £200/yr.

If the cost is high enough, then it’s probably cheaper to buy a new energy-efficient server, which then lets you buy something that will run any Linux distro you want.
