When I go somewhere and see a computer, I wonder what kind it is, hardware it has.
I needlessly buy or upgrade my computer. I have two desktops in my room, I own 5 laptops, including 2 broken ones. I used to buy a new laptop every year even though I didn't need to. I like the the feeling I get when I get a new computer, even a previously owned one.
I like the feeling on installing Ubuntu on it. If I was trapped in a building over night, you can almost guarantee that I'll be installing Ubuntu on computers. I get a rush from replacing Windows with Ubuntu. I'm fussy about hardware. I used to be about software until I switched to Linux, now it isn't so bad, unless I have to use one that has Windows. I change some of the settings to how I like it, change the language to English UK, put the icon the auto arrange, if not already, turn monitor to warm settings, etc.
I recently bought two monitors, even though I didn't need to, because I like the look of them, and the one I had was too big.
I have a SSD that I use for an external with Ubuntu on it, set up the same as my other PCs, with my music on it of course. I connect it to other computers when I can, like a public computer. I enjoy that. I always check what hardware it has, for curiosity sake. If I like the monitor or something, I write it down, if I want to replace mine in the future. Sometimes I replace my computers, even though I don't need two, just to have that new computer feeling, luckily I'm more keen on saving my money, so I don't do that often. If I was rich, I'd have the most expense PC I can build and have one in every room. I bought a laptop, just because it was touchscreen, and I think that is cool.
Last year, I upgraded my cases to Antec VSK4000 with USB 3s. They are a simple, shiny case, nothing too fancy, which is what I like.
I keep each of the computers setup the same, same software, generally the same hardware, ASUS motherboard/monitors, Intel CPUs. It's easy for me that way, especially identical software setup.
