I missed out on buying this model for £329 a week or so ago but now it's appeared again with double the RAM and hard disk capacity for the same price. Makes a great entry level PC though I'd recommend paying the extra £11.75 for the Athlon 64 3200+ processor or ideally the X2 Dual Core 3800+ for £52.87 but that just depends how much you want to spend. The person I bought this for is still on dial up so paid the extra £23.51 (ouch) for the modem because they wanted it all internal and half-height dial up modems are quite rare.
Remember to downgrade warranty to "Collect & Return, 1 Year Service only" for this price.
