I like Gigabyte motherboards, it is the Ultra Durable/ultra cool model, which runs very cool and is very energy efficient. Just My opinion, but Gigabyte boards are some of the best. The memory i highly highly highly recommend. Its by Crucial, a division of Micron, the company that makes the high end- absolute best memory ICs out there. Oh, and they have really really cool LEDs. The graphics card has better stock fan control than most, though you will still probably have to raise it yourself. I also think that Visiontek quality is superior than the other ATi Manufacturers. That power supply is a very stable unit, i use it for my system. It has very stable voltages, great life, very quiet. It is my de-facto recommendation for power supplies.
(I also recommend this harddrive, just for sake of 160GB being very small)
