CHART NOTES: We tested all boards with a 256MB EVGA GeForce 7800GT graphics board, 2GB of Kingston PC-6400 DDR2 memory, and two 250GB Western Digital hard drives configured in a striped RAID array. We tested Intel boards with a 2.66-GHz Core 2 Duo E6700 CPU. We tested AMD boards with a 2.6-GHz Athlon 64 X2 5200+ CPU. The first number listed for peripheral ports indicates those located on the back panel of the motherboard; the second number (following the "+") indicates ports located on included expansion brackets (which will occupy an expansion bay in the case). Most boards also have additional internal port headers to which additional expansion brackets can be connected.
