Mothers PC has died - advice on pre-built system

[Furton]

Mothers PC has died today, think it's the motherboard and don't have time to re-build with a new motherboard (was an old Opteron 144 system).

Out of these two cheap system which is the best? Been out of the computer scene for a while now so could do with some help.

Cheers, didn't notice the difference in RAM. Does anyone know if either of them is quieter?

Just got round to setting up the PC and it's only come with 4GB of RAM, not the 8GB advertised. Looking at the product description now and it says 4GB of RAM. Feel a bit cheated!
