first time pc build help

[ro88o31]

ok all im new here so firstly if this is in the wrong section i do apologise,
but im looking to build a pc from scratch as my current set-up is on its last legs and i dont mind doing it over a longish period of time as a small project.

what am i looking for my new set-up to do?
well i do watch a lot of bbc iplayer 4od and the likes
i do have a reasonable music collection id like to put on and stream to my xbox360
i do need the ability to write dvd's for some amateur film making im going to be doing
and would like a reasonably fast upto date and future proof (in the respect to being able to upgrade at later dates)

my budget is quite low at around the £250-£300 area it can be stretched slightly as i can do a bit of overtime here and there as it will be a slight project so could any of you help me with a slight spec? also i do not need a monitor mouse keyboard as ill just use what i have for now.

thanks for your help guys

ok guys ive just looked over your recommendations and if it helps a few points worth mentioning.

1, regarding the video editing it will be very basic as in windows moviemaker will be more than up to the task of what i need for the projects i will be undertaking.
2, a 500gb HDD would not be a problem as i will be getting a external 1TB HDD at a later date the internal HDD would be just for the OS and any other programmes i would install.
3, i wont be overclocking this set-up as its not what i have planned for it, once its built and running i may be tempted to put more money into a 2nd pc with the aim of getting the most possible out of it.

would i have any issues with any of the above internals using this case? casecom 6788
