It's gonna look the same as it is now, only thing is the internal guts are changing. I have two computers (well three if you include mobile) in my home office setup. My main workstation is in this hunking big beast of a case (Coolermaster Cosmos II) off to the right. Getting all new components to accommodate 4K video editing among other things.
This is where I do most of my editing/compositing work. There's a PS3/Xbox 360 under there which is hooked up to an HDMI hub that feeds into a capture card in my computer. Kind've hard to see but I have shuttle jog controller there on the right next to the mouse. Up on top there's a set of 'monitor' speakers by Audioengine with the input fed via an external DAC. And most importantly, a few Ivy figures and Pyrrha as well.
Behind this on the opposite side of the room off into the corner is my dedicated "artstation" where I do mostly "art". I have a Wacom Cintiq 13HD draw-on tablet here and another monitor mounted on an arm extending from the wall. I leave it mostly in the vertical position as it works well with what I do over here. Both computers, all the computers are networked together of course so files are interchangeable along with an 8TB home NAS running in the background. There's another assortment of figures mostly characters from various videogames but a few from anime. Yes those are two naked female figures on the desk - which are beautifully crafted and make excellent modeling art subjects. - oh and yeah - that is DOA Tina "oppai" *breast* mouse pad. Despite what you may think, whether you believe it or not, these kinds of mouse pads are the most comfortable and ergonomic mouse pads ever made simply because the amount of gel-cushioning added. I guess you can use it as stress reliever from time to time too ~lol (if only they made SC pads right?)
Adjacent to this is a gallery of figures, some Gundam models, and all things otaku I guess. I make it a business to visit Akihabara whenever I go to Japan =)
Don't need much in lighting since all these accent lights give the room a nice ambience. Just put on some cool easy listening music and I can just relax the night away...
