Hello there,

I live in Greenacres Florida. You can do much better than replacing the motherboard and keeping with the old system.

I bought my pc from Palm beach County when they were selling the old stuff off. (happens about 1 time per month.)

Check with your county government. Ask when they sell off the old items.

My pc is a Dell Precision 650. 2 gig ram, 3.06 ghz Xeon Processor.
It was the "Caddy" of computers about 3 years ago. Still keeps up with the big boys. Total cost? 125 for the computer/ 40.00 for my 21 inch monitor (older tube type not flat screen) 60 bucks on sale for the ram.

Called Dell, they sent the restore disk for 20 bucks to install windows XP.

A little bit of hunting can go a long way.
Check ebay, Stealitback.com Overstock.com ect.

Good Luck and if you ever come to Florida, Drop me a line ahead of time, I'll tell you when the sale is :)
