Should i upgrade, and if so to what?

[ScoobyDoo]

My current spec is:-

Biostar case
Xp2500 processor
1gb PC3200 RAM
Win PVR-150MCE TV card PCI
Nvida Fx5200 AGP graphics card
250gb IDE Samsung drive
Sony DVD writer
Windows MCE


Ive just brought a LG 32inch LCD TV and at present I use the above PC as a media centre PC. What i now require is a media centre PC which is capable of playing high defination footage along with the ability to play counterstrike source on the lcd tv.

I was thiniking about keeping most of the components, just changing the case, CPU to a A64 3200 (939), and change the graphics card.

Ive looked at Shuttle cases which I really like, but some dont have both PCI-express graphics along with PCI expansion which i need for my PCI TV card.

What would you recommend???
Budget for case is around £220

Think the silver stone sugo might be the best bet for me.
Looking at the Shuttle cases they dont offer what I need, ie PCI-Express graphics, and a standard PCI slot for my TV card.

Im defo going to get a 939 based AMD64 processor, want to keep my current PC3200 1gb RAM, so ill have a look what motherboard goes best with the sugo.
