I am also a proad owner of Chieftec. I am using Cheiftec BX-03B-B-SL for my own personal PC and my other PCs is using BG-01B-B-B. Here is my current spec for my personal PC:

Intel Pentium D 3.0GHz 830 Dual Core
Corsiar 512MB DDR2 533MHz Memory x 2
ASUS P5LD2 Motherboard
ASUS EAX1300 PRO/TD 256MB PCI Express
Western Digital 250GB SATA2 16MB Cache Hard Disk
ASUS 16X DVD-Writer
ASUS 52X32X52X CD-Writer
Cooler Master 480W Real Power
ThermalTake Copper Heat Sink

My next project is to get better monitor, keyboard and mouse. My current on going project is AMD PC. The only thing I am still thinking is about the CrossFire Technology. Any advice?
