My favourite Springdale Chipset is also known as the "Intel 865PE Chipset".
There are plenty of good boards availabe using this chipset, I bought the Gigabyte GA-8IPE1000 Pro and it was cheap and fully featured.
http://www.giga-byte.com/MotherBoard/Pr ... %20Pro.htmYou may be able to use your old RAM chips if they are DDR, but you really want 2 x 512mb PC3200 DDR Ram Modules (400mhz DDR), these 2 modules need to be identical and high quality to run the RAM effectively in Dual Channel mode on the Springdale mainboard.
Don't get too thrilled over the 2.4 ghz Celeron, it's still just a cheap and nasty CPU and the speed won't overcome the CPU's design limitations. A P4 CPU is expensive for a reason, it performs!
Well, now for the alternative advice...........
Try checking your mainboard manufacturers website to see if a BIOS upgrade on your present mainboard will enable you to use your 2.4ghz CPU. It's possible.
OR........ Get the cheapest mainboard you can that will fit the new CPU, as it isn't ever going to be a power system anyway.
Good Luck
