spec me a £400 shuttle rig

[DeeJay-Mo]

I'm giving away my trusty Shuttle SK43G to my auntie, so I'm looking for a new shuttle for my bedroom. I've already got 2GB DDR400, 200GB HDD, choice of black or beige DVD±rw. All I need is the shuttle, cpu and gfx card (probably chuck a floppy/card reader in there too).
I will be using the system for games and displaying videos on an lcd, as well as occasional downloads. My current thoughts are to go for a skt 939 Athlon with 1MB L2 cache, but I'm open to suggestions.
Spec away guys.

Thx.

Thanks for the replies. I'll probably go for the Venice 3700 and the SN21G5. Still not decided on the graphics card yet tho. From your suggestions it seems that it's better to go for a better chipset with only 256MB ram, rather than something like a Leadtek GeForce 7100 GS Turbo Cache 512MB. Is that the case?
