I was planning to build a PC with a mATX case I have. Here are my plans:
-Abit NV7M for the MB
-2x512MB DDR SDRAM
-20GB 5400RPM hard drive
-one optical drive, DVD or CD-RW
And i need some help with the CPU.

My PS specs are:
Delta Electronics, Inc.
Model: DPS-145PB-100 C REV:2
Input:
100-120V~/4A
200-240V~/2A
50-60Hz
Output:
+5V/15A
+12V/5A
+5VSB/0.72A
+3.3V/10A
-12V/0.4A
150W MAX.
+5 & +3.3 total output power can't exceed 95W

So can anyone help me out on choosing the best CPU for this?
