Well, the burden will not come from the devices but instead will come from the load you place on them. So, the real question should be: how do you intend to use the machine? The only hardware recommendation I can make would be to watch out re: the IDE disks. You may not be able to use DMA on all of them and that will really take the cpu out for lunch. SCSI is the better choice there if you intend to load the disks down. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
