My computer IS my TV and vice versa. The line between which device is which gets blurrier every day. That said, keep the computer in the other room. It’s capable of generating white noise if you miss it that much.
If you have two (or more) people in your house, put them in different rooms so that they can both be used at the same time without interference. Otherwise it probably doesn’t make much difference.
I vote bedroom for the same reason. Mulitasking is overrated.
Having said that, my TV, computer, and bed are all in the same room. In my last apartment they were all in different rooms. Different living arrangements make for different… well, living arrangements.
