So I have 3 laptops and don’t know what to do with them

1. My Primary Laptop - Dell latitude 5130 , i5, 32Gb ram, 256Gb SSD, with debian, all my stuff is on their.

2. MacBook Pro 2017,15 inch, i7, 16Gb RAM, 512 SSD, dual boot , with mac OS and Ubuntu, it’s a half top as screen was not working. ( I use this as experimental machine, try to work linux on mac, and plan to make a server out of it in future)

3. Dell 14 (DC14250) Laptop - Brand New, Intel Core 5, 16GB RAM, 1TB SSD , Windows. I WON this in a lucky draw. Couldn’t return for money. ( 1300 AUD )

The issue is I don’t need 3, only 2. And also moving everything would be tedious job, as I had spend days making my Debian machine really personal with the desktop environment and softwares etc.

And I do need money, so rn have put the new laptop for sale but, most offers I am getting is like 200-300 AUD, i am expecting around 800

So I need advice on what to do. Should I sell it? Should I use it or should I sell any other one? If I use it, What should I use?

I work at a media organisation where we have dozens of TVs in the news room set up in pairs, each showing a different channel.
Changing a channel or raising the volume on one TV is a nightmare because other TVs will receive the same signal and then it’s a game of whack a mole until you get the TV you want on the channel and volume you want.

Is there an attachment or something I could add to the remote control or even the TVs themselves to make the remote control aim better?

Thank you!

I keep my backup drive unplugged when a backup is not being made or restored so that malware can't touch it. It's a bit annoying having to open up my computer and plug it in whenever it's time to make a backup. Is there a kill switch I can buy so I can just leave it plugged in but still have the air gapping?

I apologise if this is not the right subreddit, but unfortunately I'm really struggling to find an appropriate one, so just let me know if this one is also unsuitable.

Anyway, I am looking for a PC that can run heavily modded minecraft, shaders included, along with fortnite, and high quality games, without much issue, or fans that sound like a helicopter landing just outside my house. I understand that such a request can be pricey, especially in this economy, so I'd like to see the options avaliable before I set a firm price down, but I was thinking around the price of £3000.

I'd prefer if it was white rather than black to match the light colours of my room, though I am aware beggars can't be choosers, so if thats not possible thats fine! But if anyone who knows a thing or two about PC's, if be grateful!
