Hey

I'm considering getting my desktop from the downstairs living room and putting it in my room, as I want a little more power than my laptop can offer me, plus desktops are... better.
Anyways, got a few questions about it, and hoping I can get some answers here.
Firstly, is it particulary difficult to upgrade RAM? Currently my desktop only has 512mb of ram. Obviously I want to upgrade that.
Secondly, the only way I currently get an internet connection upstairs, is through wireless. My desktop doesn't have a wireless adaptor. So my plan is to move my router upstairs. The cable between my modem and router is an RJ11 to RJ45 (I think thats the one) but it's only 1m long. Would it be possible to buy an ethernet connector, plug one end into the RJ11, and the other end into, say a 50m ethernet cable, and run it upstairs?
Thirdly, I was thinking of using my HDTV as a second monitor. My desktop typically doesn't have a HD output. Any ideas? The options I have are:
Desktop:
s-video
VGA
USB
TV:
Scart
Component
HDMI
Thanks!
