i'd have a long and wide boi desk, L shaped to boot. triple 144hz 1440p monitors, all floating and cable managed to perfection. a full size fully hotswappable mechanical keyboard (realized recently how useful the numpad is to me lol) with lubed Kailh Box Whites. Pwnage Ultra Custom Symmetrical Wireless gaming mouse with a 450x400mm plain black mouse mat, probably from Steelseries or HyperX or whatever. Logitech BRIO webcam. Audio Technica AT2020+ USB condenser mic to the side, pop filtered and shockmounted with a heavy duty mic arm.
to my right will be a water-cooled Ryzen 9 5900x/RTX 3080/64GB RAM system with a full tower mesh case and looots of SSD storage (Windows 10 & Linux dual boot btw). once again, cable managed to absolute perfection. crud load of fans. just a few lights though because i can't bear to have my system look like rainbow barf. with the space i have left on my table, i'll have some high end, lightweight, 14 inch, long battery life laptop (probably from Lenovo or Dell or whatever, and it'll also be dual boot) for portability. it'll have its own wireless gaming mouse too. most likely something more affordable, like the G304 wireless.
chair will be a Herman Miller, either an Embody or an Aeron. headphones will be a pair of black Sennheiser HD 598s. and since i'm going headphones, the room needs to be air conditioned. windless if possible. a cool 15-17c is ideal for me. it means i'd be able to wear hoodies, sweaters, sweatpants, and socks. i like the style of those, so i'd be happy to.
lastly, i guess my phone will be some OnePlus flagship or whatever lol. something with 8GB RAM, and 128GB+ storage is overkill enough for someone like me, who just uses phones for browsing and communication. i will definitely just get it as a status symbol at that point.
