I like them for the ease of changing components.
Follows is a list of what I used for this one:
Intel 965XE
Evga 758 X58
Alphacool Liang pump
Swiftech 320 rad
Swiftech GTZ Apogee wb
EK NB/SB/Mofset wb's
Silverstone Decathlon 1000w
WD 500GB - WD74GB
Lite-On DVD
Zotac 8800 GT (x2)
Results so far...
I have since lowered voltages and will test later with HT on to monitor temps.
