"The MSI MEGA mPC945 system is based around the Intel 945G and is compatible with all Socket 775 Intel processors. Under the glossy white hood, the mPC 945's two DDR2 memory slots will support up to 2GB of dual channel DDR2-533/667 memory. In terms of storage space, the system has one 3GB/s Serial ATA II channel and one IDE controller. There is onboard video care of the integrated Intel GMA950 graphics card, it comes part and parcel with the Intel 945G chipset. If you want to use a better videocard the system will accommodate single or double slot PCI Express graphics card. PCSTATS would advise a Geforce 7800GTX or equivalent videocard if you plan on doing any gaming at all... as you'll see in the benchmarks."
