Agharta:
God knows what sort of case, power supply, RAM and motherboard you are getting on a cheap system like this and only 1 year warranty.
For very little more (£15) you could build you own at Scan with named components from major manufacturers (Asus, Silverstone, Hitachi, Corsair) with longer warranties. E.g. 3 years for CPU, Mobo, HDD and longer for the RAM.
I think it's fair to say you get what you pay for, and if you're after a cheap and cheerful machine then I'd say it's a good deal. I think your comment about a cheap system also applies to the hundreds of cheap Dells that appear and go hot on HUKD.
