I have the A7V, and so far have no problems. I have a network card, and have put in the extra USB's. I say the mobo is great, letting you overclock easily. Put your sound card in PCI 3, install the VIA drivers FIRST, get the latest promise stuff from ASUS (build 25), but dont bother flashing your BIOS until you need to, and always save the previous version (read the manual!). You should be fine. If after plugging everything in, the system doesn't seem to work, try shorting the battery momentarily with a screwdrive. Both times I put a system together using the A7V, I had to do this (scary stuff, when the system seems dead!). Good luck...another tip, in Bios once you know where all your components are, and where to boot from first, tell the bios yourself, it saves startup time. Also connect the CD to master ATA66, and the HD to master ATA100, with an old cable as this improves performance. Good Luck!

AN ASUS A 7 VEEE!
