Ivan,

From past experience I can recommend a company named Velocity Micro. I purchased my recent system from them and they rocked, both in build quality and customer service. They are located in Richmond Viginia but the good thing is, if your computer needs warranty maintenance they will contract out a local service person to physically visit your place of residence to repair the machine.

The good thing about this company is that they use off the shelf products when constructing your computer. They DO NOT use proprietary hardware in any way shape or form so you know exactly what the specs/performance of your hardware will be. They will also tune your computer to your specific needs when they build it.

I've had my computer for over a year and have not encountered any issues with it. This is very important to me because I have a freelance design business that depends on a trustworthy and dependable computer. I can honestly say that Velocity Micro has delivered on their promise of quality.

Here's the link if you're interested in them.
