my tank is in my bedroom too.. i'm ok with the noise and all it's the damn heat from the chiller which really gets to me sometimes...
as for canister, I would suggest against it, get a proper sump, build/order a proper stand, do it right the first time...
also, one of the best advice to give newbies is this, "if you are serious about the hobby, get the biggest tank you can afford". Why? Because sooner or later your hands will get itchy and you'll want to upgrade...
Trust me, I've been thru a 1ft cube with hang-on filter all the way to my current 2.5ft with sump and all that...
Have fun!
