Talk to TilDeath, he's the man you can ask questions and he will give you the straight up honest answer.
http://tdcomputersystems.com/Here's his website, I chose a cheap and crappy company to build my system because I frankly don't have the time for it, I was getting a third rate system for the same price as what he put together and he gave me a first rate system.
Same money, third or first... yeah either give him a call or check his site out - he's quite happy to talk to ya.
