Get an nForce2 chipset motherboard. Don't buy stuff that's already outdated by 3 other products (KT333, KT400, nForce2)... especially for that insane price. Get a good Antec case with a 350 watt power supply and an Epox 8RDA+ for less than $200 total.
Then grab up some PC3200 RAM and an XP2100+ Processor for a real rig.
A cheap case and cheap power supply will annoy the hell out of you. Cheap power supplies have fans that start to rattle after about 6 months, cause reboots and lockups because they can't deliver enough power for all your acessories... and cheap cases have sharp edges that leave scars, very thin aluminum construction that results in a warped case that makes the side panel hard to put on, LED's on the front that get more dim as time goes by, drive bays with holes drilled inaccurately so drives sit tilted when screwed in, and plastic that discolors.
