Keyboard, HTPC, TV card and mini keyboard

I'm from the UK and looking for a cheap set of items I would like a case with enough room to fit a DVD player, an 8800 gts and TV card but still as small as possible to fit under the tv in the cabinet.

Also something to control it with from the couch with the ability to type and with mouse control or touch pad.

All this from under £100 is it possible? or do I need more money?

My first build is great but the case has let me down no room for expansion.

So this will be my second build My MB is a striker extreme 775 with 4gb of ocz 1066 of ram.

many good stuff here http://forum.xbmc.org/showthread.php?tid=94199

For the case I am not sure maybe the SilverStone GD05 I think its one of the biggest cases in that format.

For a Keyboard I like my logitech K400 its good if you want to use the touchpad and write a bit.
If its more for remote control use and only a few clicks maybe check out the smaller ones from eskros RF Keyboard thread.

The K400 is about the same size as a Notebook keyboard (including the touchpad).
