Where can I find a BTX motherboard with an LGA 775 socket?

Question

I have a Dell XPS 410 which has a Dell P965 BTX motherboard. I want to upgrade the motherboard and replace the CPU...but I cannot find any BTX sized motherboards with a 775 socket.

Here's a list of Intel socket 775 motherboards.

I've searched newegg and a few other places with no luck, where can I find a suitable motherboard?

Also, is it even worth the effort to upgrade just the motherboard & CPU on an older PC, or should I consider getting a bare bones system instead?

Update: The closest thing I could find is this: http://www.geeks.com/details.asp?invtid=D955XCS-PB&cat=MBB

The only problem is the 1066 bus speed. My goal was to upgrade the motherboard so I could run a chip with a 1333 bus speed.

Answer 1

the problem with Dell: they're using custom-made mainboards, you can't just buy a board somewhere 'off the rails' and fit it into a Dell computer. either you can order a mainboard that fits into the XPS 410 from Dell or you will need a new case and PSU as well.

on another note: Dell computers are pretty solid work horses, but you can only upgrade very little, after that its 'we gladly sell you a shiny new faster computer' and they're certainly no overclocking material. so if you're the experimental type, then Dell is not for you.

Answer 2

Ah, more research shows the BTX form factor was cancelled.

However, future development of BTX retail products by Intel was canceled in September 2006. A proprietary form factor is now used by many companies

That's unfortunate, I suppose my only option is to buy a bare bones machine and salvage whatever components I can from the old machine.
