My last MB was a BH6, had it for three years and placed several hard drives in it over the years. I can assure you it will take "newer EIDE Harddrive's" with no problem. The only kink is that it will only see up to a 60 gig drive - 67 gig to be exact (bios limitation). Check the abit website for any further bios upgrade that will address this problem. Check to see if the drive or the website doesn't come with a utility to fool the computer into seeing larger than a 60 gig drive. Some manufacturer's supply free downloads that address this problem, ie: maxtor has a utility, but has cahnged it to work only with their drives!
Also, if you want to gain the faster disk access/transfer speeds, ie: 66, 100 or 133, you can easily add a "promise" card that will access the drive at it suggested potential. I used the promise66 card for over a year with real benefits to overall system performance. However you'll need the newer 100 or better 133 card for the newest drives. Though I have no first hand experience with the 100 or 133 cards the older 66 was a breeze to install and both windows9x and XP recognized the cards and installed drivers for them (win98 required an upgraded driver from their website but still worked without it until then). Another bonus was that I was able to place more than the 4 drives. With the addition of the promise card I could put on up to 8 drives. Though not usually an issue, I ran burners, cdroms, dvds as well as a couple hard dives, something I couldn't do with just the onboard ide connection!
Sorry for the long post but I hope it answers you question as well as gives insight as to other possiblities.
