Bought a Dimension 9150 as my 2nd media pc in the lounge which I have networked to a self-built monster & laptop. All depends on what you want out of the machine but this model works very well indeed & no issues with the network or high-end performance.The 7.1 surround is brilliant & graphics are very good too(hooked upto 36" digital tv). whichever you choose, I advise the same as Conan as far as upgrades go. Take the memory upgrade when you buy the machine as later on, it can get a little expensive.
