Cheap PC

[mavers]

My parents main PC has finally given up. As the PC is quite ancient (from 2003), I'm looking to replace it with something cheap.

The only reusable parts are the Lian Li case and the hard drives. Not sure what the PSU is.

Their requirements:
Occasional web browsing.
As they need a machine to backup their laptops I was considering installing WHS (currently, they were backing up manually to the pc)

The PC will be hardly on, so I’m looking to spend as little as possible ~200 quid.
Onboard video is fine,
CPU/RAM/Motherboard
Possibly a PSU

Thank you for the replies.
Reason behind getting them a new PC, is that i want to get them a XBMC thin client at some point, so this PC could serve all the media.

I'm tempted to buy them a thin client now, and then building a server later.

What are the latest thin clients out there? I remember the Acer Aspire Revo R3700 was pretty decent over a year ago. Or are there better things out there now?
