I want to move away from building my own computers from separate parts, mostly, because of the increasing number of computers we'll be needing soon. So I'm looking for a computer systems integrator/vendor business in the USA, preferably nearer my area, that can do this job. They need to know how to build machines for, and support the hardware for, Linux users. That includes selecting components that work in Linux when I don't specify particular models for that. They need to be able to build fully custom computers, which means not a limited set of a few preferences (for example what System76.com has). They need to be able to support the hardware under Windows as well. BSD is a plus.

Today I'm looking for workstation computers. High end graphical card with 1 GB RAM, one or two CPU socket, quad/six core capable, 8 GB ECC RAM using only half the memory slots, expandable to at least 32 GB, 4 ports of SATA-II for hard drives, 32 GB SLD PCIe flash drive, hot swap bay for hard drives with empty trays (hard drives will be bought separately), and swappable 600 W power supply (can be cold-swap non-redundant, but hot-swap redundant is OK). Name brand components (e.g. mainboards from ASUS, SuperMicro, Tyan ... etc).

Anyone know of a vendor like this?

Have a browse through here.

Some possible companies exist in the list. Lots of others are dead links. Sent some email to sales departments asking, though none of the web pages suggest what I'm looking for. One thing I see is that none of the sites with "configure a computer" web pages offers the choices I'm wanting. For example, choosing a motherboard. Most also force particular choices such as at least one hard drive, yet none of what I want. I'll see who answers their email.

What is so hard to build the computers your self. Hire someone that will take care of the support. If you still insist having someone else to do it, go through the yellow pages and find local computer stores. If you have someone else build the computers and support them, what will you do if they go out of business or they decided to not support you anymore. You are screwed if this happens. My community college built 1000+ computers themselves.

I suggest get an Apple Mac Pro. It suits your specs, but you need to add a better video card separately because Apple does not supply quality video cards for the Mac Pro. Mac OS X is a form of BSD. I do not recommend Windows, so only use Windows unless you have to use it. Mac OS X is a better OS compared to Windows. The following video card is the only high-end model from nVidia with out modifying the firmware your self.

EVGA GeForce GTX 285 MAC Edition (01G-P3-1080-TR)

FYI, a workstation computer does not need a redundant power supply. That is useless.
