i own a pentium 3 HP Kayak XU. It uses 68 pin SCSI HD and has more ports for other SCSI devices. Isn't SCSI outdated now? well, now that we have sata. i wanted to put more scsi hd's since teh stock 8gb is kind of small. and also, why is ecc sdram expensive too? the computer only has 128mb ram and i would have wanted to put more memory, but seeing how expensive the ram and the hd's are, i kind of think investing money in this computer is a waste of time and money, no? i mean, it was an awesome machine fro its time!
