I wanted to install one in my8 AlphaServer 200 4/100 (just like the Stuart's, I think.)  > I opened one up, and found it had an internal 68-pin connector? and cable.  (I've since dismantled at least one other and found B it was a 50-pin connector and cable.  They were all labled RZ28-VA on the outside, IIRC.)  A I got a 50-pin to 68-pin adapter at Microcenter, which cost about B $10-15, I think (more than the drive did), and installed it on the= drive and then connected the 50-pin cable to it.  Works fine.   @ This is a black plastic about 2 inches wide, 1/2 inch thick withA a male 50-pin connector on one side and a female 68-pin connector B on the other.  It makes the drive about 1/2 inch deeper (front-to-A back) when plugged in, but there was room behind the drive in the  case.   < It should work fine with an RZ29 as well, but you might have= cooling problems.  I suppose you could always duct-tape a fan ; to the outside of the case to blast cool air through it, if = necessary.  I think there is plenty of power to drive it, but @ you should check the manual.  (I can look at the specs tomorrow, if you don't have one.)   A I'm sure this isn't supported, but if you are mucking around with . RZ29's and A/S 200's, you probably don't care!    
