Here's an Asus H67 board that has ports for 2 PATA/IDE drives and 6 SATA drives (2 SATA3/6GB/s)

For about $260 you'll have 8 GB of DDR3 1333, SATA3, USB 3.0, and a 3.1 Ghz dual core processor (with Hyper-Threading, so it's like a quad core) which should be 10 times faster than your old rig. A 350 watt PSU should be enough until you get a decent video card, after that I'd go with at least 600 watts.
The H67 chipset doesn't support overclocking but does support onboard graphics, so the Intel HD 2000 integrated graphics should get you by until your video upgrade. Asus is usually rock solid and I've seen excellent reviews of the i3 2100 so you should be good to go, and when you replace your IDE drives with SATA it'll be even faster.
