Overall it appears to be a fairly good buy. My only concern is with the power supply chosen. The power supply is one of the most critical components to consider when building a system, but is often given little consideration. Everything in the computer is dependent on it for clean, sustainable power; especially the cpu, chipset and video card(s). How well they provide power to components and dissipate heat is extremely important. Power supplies are not built alike even though they may publish very similar specs. The cheaper ones usually use cheaper parts such as cheap heat sinks that are often inefficient and short-lived. I am not familiar with the Dynapower PSU and find little comparative information about it on the web. This does not mean it is not a good one, but its price is somewhat suspect. A better known, reputable name-brand (such as Antec, Enermax, Fortron, CoolerMaster, Thermaltake or Zalman) would have been preferable for a gaming system.
