4 SATA, 2 eSATA.
2 PS/2 ports

Core unlocking support.
Price (4-25-10): $60 from newegg.
ASRock is a spinoff of ASUS, so they should be relatively trustworthy.
The big plus of this board is the price. The minus: 2 less SATA ports than most, and no COM port (most don't have these anymore, though).
Tweaktown has a review. It doesn't really say much you couldn't tell from reading the specs.
Newegg customer reviews are mostly positive. Out of 74 reviews, the only negatives that showed up were
- The raid support is not very stable
- One person had lots of stability problems that sounded like a bad MB
- One person had a heat-sink pop off.
- 3 people had the board fail within a few hours of first use (I wonder if it is heatsink problems?).
- One person found that a CPU which could be core-unlocked on another MB would not unlock and run without crashing on this one (plenty of other people comment that core-unlocking did work for them).
Sounds like a reasonably high quality board, especially given the price. On the other hand, $25 more buys you an ASUS MB of similar specs + 2 more SATA ports.
