Okay, I've got a P4 3Ghz 512Mb RAM with a 256Mb Nvidia graphic card and a total of 160gb hard drive with a 2Mb broadband connection running Windows XP. I've also got the bare bones of an old P3 500Mhz which I could probably cobble together a spec of 6Gb Hard drive, 128Mb Ram with a 64Mb Graphics card. It's got an internal 56k modem. So the question is what, if anything, can I do with the old P3 once I've rebuilt it that will give me some kind of benefit on my P4? This is more a project than an actual necessity, I just want to see what's possible. My main use for the P4 is image and video editing and using it as a kind of media centre. Limitations are a budget of £50 on any necessary cables or parts (I don't own an ethernet cable - so take that out of the price) and space in my flat. While I've got a spare monitor, it would not really be practical to set up an entire workstation unless the idea had mindblowing benefits.
