I try to build a server, web server, ftp server, dns server, mail server, all in one box, with Quadro 6600.
I can't afford to have Zeon processors but Q6600 is multithread so I thought I may get benefitted with using Q6600 when/if multiple users visit my website and browse at the same time.

I would like to know if I made the right decision or what other alternatives can I get in terms of building a server computer with a limited budget.

Any comments will be appreciated.

It's a Good decision, LGA771 XEON Servers Utilize Buffered RAM, while LGA775 XEON Core 2 Duo- Core 2 Quads don't. The XEON is only a slightly better binned Chips with a premium only for assurance of Cooler and slightly more Efficient CPU's other than that many of those chips came from the exact same Piece of Silicon.

Don't use the on board software raid get a pci-e raid card x4 or better and maybe a very low end video card pci is ok or maybe a pci-e one but if the board only has a x16 slot and no x4 or better you may want the raid card in that slot.

Very solid advice. The onboard SATA ports on most motherboards cannot handle the traffic caused by a disk array of any size, so putting a dedicated control card on a very fast PCIe bus is a must.

And as far as the OP's Q6600: you don't need that kind of power for being a network server unless you are on a very fat pipe and expect to be serving thousands of simultaneous requests for files and such, or you run a Web frontend to a database on the server. A simple http/ftp/DNS/file server does not need to be powerful at all. You'd see no difference between a Q6600 and something much less powerful like an Athlon 64 X2 BE-2300 or a Pentium Dual Core E2000 series chip. Also, the slower chips run considerably cooler than the Q6600. You need good disk and network throughput before you need a fast CPU for your kind of server.

Thanks for the replies.

What motherboards would you recommend for less than $200?
I didn't get a reply in the motherboard forum, so I'm asking you kindly experts here.
