Custom Built PC's will almost always outperform similarly priced, store-bought PC's. I can build you a computer that will be cheaper, more reliable, quieter and/or run cooler than 9/10 pre boxed PC's that you would get at a retail store. The biggest advantage is that the computer can be tailored to your needs; money can be spent where it would be the most useful. Any computer I build comes with lifetime discount for on-site-when-possible tech support.
Home Theater Installation and Consulting is necessary most of the time to achieve the best possible, movie theater environment in your house. Not only can I make suggestions on what to buy, I can install and optimize your system and room to achieve the results that you paid for in your TV and speaker system. Most services can plug in your equipment and get something working, I can set up your system properly and 'tune' the room for the best possible sound in the most practical situation.
