I'm speccing a Conroe pc for a friend. The key components are as follows: Motherboard Abit AB9 (Socket 775) PCI-Express DDR2 Motherboard (I know the Gigabyte DS3 is same price but this is my friend's first time building and I don't want to recommend a board with memory compatibility issues) CPU Intel Core 2 DUO E6300 "LGA775 Allendale" 1.86GHz (1066FSB) - OEM Cooler Zalman CNPS9500-AT Aero Flower (Socket 775) CPU Cooler - or - Thermaltake Blue Orb II Socket 939/754/775) CPU Cooler - or - Scythe Ninja Plus Heatpipe CPU Cooler Memory 1Gb (2X512Mb) Corsair TwinX XMS2, DDR2 PC6400 (800), 240 Pin, Non-ECC Unbuffered, CAS 5-5-5-15 Power Supply Enermax Liberty 400W ELT400AWT ATX2.2 Modular SLI Compliant PSU I won't bother listing the remaining parts. I'd just like a few questions answered about the spec mentioned above. 1) Is the 400W power supply going to be enough to power all that + one hdd + one 7600GT + one DVDRW? 2) Are there any nasty things (other than questionable layout) I should know about the Abit motherboard, such as if it doesn't work out of the box with an Allendale? 3) Which cooler is most likely to fit on the motherboard I've chosen? p.s. If you would like to suggest a change to the spec, please suggest something cheaper or equal price to what's there already.
