The VIA EPIA series is an incredibly cheap and versatile platform. They have opened up a large modding opportunity that many people have leapt at to create some weird and wacky designs ranging from In-car systems to making an x86 G4 Cube! The M9000 and V9000 are virtually identical, however there are a few excellent additions in the M9000 inventory that make it even more appealing, especially for the price. To name a few - FireWire, MPEG2 Decoding, 6-channel sound, DDR Support.
