Trying to build a computer for my missus, budget is £400 max and it will mainly be used for web/work etc with the odd bit of the sims 2.
Catches are that it will be running in a rather warm conservatory so heat is what killed the last one, because of this it probably won't be overclocked and i've bought a decentish case/heatsink in order to stop dust buildup (which is what caused the other one to die combined with the heat) and keep things cool and relatively quiet.
Anything wrong with the spec and any suggestions on how to improve it? Thanks in advance.
