Use-case wise, I'm a developer by trade and a gamer/PC enthusiast (is that still a thing?) off hours. I.e. I spend a lot of time in front of this thing. I also have something of a fascination with physical workspaces and desktop environments (from a HCI point of view), though I've never managed to move the needle much in that respect.
>> What room do you use in the house?
In a house with a few (unneeded) bedrooms, so one of those makes for a decent-sized office.
>> Do you have a special desk?
Not really - Ikea Alex/Karlby worktop job, same as all the YouTubers use. This whole setup is basically your stereotypical YouTuber/streamer rig (though I do neither of those myself). In fairness to those folks, the Karlby-Alex combo does make for a very simple and effective desk. Good size, very stable (this 180cm worktop weighs a good 30kg by itself). Never had much interest in standing desks.
I do have a second desk set to the right-hand side of the main one; simple Ikea table with a large roll of paper on a reel pulled across it, padded underneath, lamps overhead. The idea is to use that as a scratchpad/brainstorming space to swivel back and forth from, though frankly it hasn't seen much action yet.
>> What monitors do you have?
Triple monitor setup for work, just about. Main monitor is an Acer 27" 1440p 144hz IPS, very nice. Also have the 15" laptop screen to one side, sitting on a simple metal stand to raise it to usable height.
And in the only moderately original aspect of this whole setup, a 10" touchscreen propped up at an angle in front of the keyboard, below the main monitor (that gap the BendDesk folks were targeting with their curve). That's very useful for breaking out extra IDE windows for search results, debug output, etc, and/or keeping IM tools handy. Haven't been using the touchscreen aspect much yet tbh, though there's definitely potential with that positioning.
Ultimately I'm looking towards a 32" main monitor, but my desired specs (4k, IPS, 144Hz) are only barely available at that size yet, plus gaming on one would need serious PC upgrades.
In the short term, a 16" monitor in a vertical orientation is the next experimental addition.
>> Keyboard? Mouse?
Gamer gear again, hooked to a KVM between my work laptop and my LED-laden-fishtank of a desktop. In fairness, better brand gamer peripherals tend to be very good for general use as well, as long as you can live with tasting the LED rainbow.
Specifically my mouse is a Logitech G903 - excellent wireless mouse, easily the best I've ever owned.
My keyboard is a Fnatic Ministreak (more obscure brand tied into esports, but a very nice keyboard). It's a TKL ("tenkeyless"/65%, i.e. no number pad) - I never used the numpad much, and I like the reduced width to keep my mouse hand in closer. Mechanical keyboard with MX Brown keys - great to type on, not very loud as those go, but still too noisy to ever use back in the office, more's the pity.
>> Do you work from a laptop?
Work-supplied laptop, yeah, though I only ever use it docked with proper peripherals - apparently unlike the entire rest of the world, I've never been a fan of laptops.
>> Do you move around the house?
No, never got in the habit of that for work. I do have a "sitting room PC" downstairs; rigged up a monitor arm to hold a 24" monitor out in front of an armchair, running off a nice little Intel NUC that's barely bigger than my fist, wireless mouse and keyboard on a lapboard. Quite proud of that setup, clean and efficient.
>> What other equipment? Microphone? Webcam?
One of those giant Corsair mousepads that extends across the desk, in keeping with the YouTuber stereotype. Actually pretty good - makes for decent mousing, plus it pads the keyboard impacts somewhat.
Chair is a Secretlab Titan Evo, because of course it is (served me well, good mid-priced chairs in fairness).
Corsair wireless headset, serves me well for mobile sound. Microphone is entirely adequate for calls, but as always with wireless gaming headsets, it's definitely not something you'd use to make proper recordings.
Webcam is just the dodgy built-in one on the laptop for now, Logitech C920 would be the weapon of choice if I ever get around to replacing that.
