I wouldn't go so far as to call Tyan a bunch of crooks, but I have been left a little miffed with their design choices. I mentioned this in another thread, but to recap, I have a Tyan Transport GX28 1U server case with built-in s2880 Tyan thunder k8s m/b. I assumed from the start that the on-board SCSI would be easy to upgrade to RAID using ZCR. Well, lo and behold, the ZCR slot is inaccessible in this server. So, I decided to buy an LSI 320-1 RAID card (I wish they had 1X versions), and on trying to fit this card in the server, what do I find?... A tall capacitor makes it impossible to fit (ultimately i had to strip the card of its backplane and fit it in another slot --messy). Ultimately, this was not the right m/b for this 1u server.
On the positive side, their server case is very well built. The hot swap drives, the SCA backplane, the cooling/air flow design, all top-notch. There aren't that many 1U cases that support 4x hot-swap scsi, with dvd-rom and floppy. The only thing missing is a scsi connector at the back for external devices.
