Hexus.net have poasted a review of the Epox SiS 645 4SDA. Here is a Snip:
"The Epox 4SDA is rather barren on the features front. We didn't have RAID (athough the 4SDA+ does), decent on-board sound or additional features such as USB 2.0. We can appreciate that the SiS645 chip set equipped boards are targeted at the budget-conscious user, but we're still disappointed that it doesn't support any of the aforementioned extras. The general layout of the board is good, however."
