Thanks for reply - have u any suggestions on a desk I want something contemporary at the same time isn't going to cost a fortune lol - I'm going to keep mac in my bedroom so don't want a massive office desk nor do I want something that's got a life span of a nat lol?
Well, I don't believe that we can give you a specific recommendation w/o knowing the space available in your BR nor its decor (assume you want the furniture to look similar?) - but for starters, just google 'computer desk' and select images - you'll see dozens of examples, many can be ordered online and are of the 'knock down' type (i.e. you will need to put the desk together which is usually simple).
NOW, keep in mind that you will need enough desktop space & storage for equipment you likely will want to use w/ your iMac - e.g. my beginning list would be the iMac (w/ KB & mouse and/or pad), printer (multi-function one if you want copying & scanning - probably an ink jet), storage racks and/or drawers/shelves (for paper et al), and an UPS (uninterruptible power supply) for battery backup if you have power outages. At my computer station, I also have a second laser printer, plus my modem & AirPort Extreme router.
Concerning your router, you should definitely learn more about the 'orange box' - DSL vs. cable, Wi-Fi specifications (802.11 b/g/n or the newer ac), and how to adjust it's settings (an app vs. a web-based URL) - there is likely a manual available someplace online (talk to your ISP) - and finally I'm assuming that your BR connection is an ethernet cable from the router; if the 'router' is central to your house, then hopefully Wi-Fi range (depending on the protocols used) will be fine.
