The Gigabyte GA-EP45-UD3R is an ATX format motherboard that accepts Intel CPUs in LGA 775 format. This is nearly identical to the Gigabyte GA-EP45-UD3LR, with one less PCI-E x1 slot and the addition of FireWire support. This is a lower cost alternative to the Gigabyte GA-EP45-UD3P, enabling construction of a home media PC that will work with a video camera that uses FireWire. This motherboard has one PCI-E x16 and a single 10/100/1000 Ethernet port, but otherwise the two boards are very similar. 6 SATA connections are available with full RAID support, and high definition audio is available through coaxial or optical ports that can run directly to a home entertainment system.
