(i really need some more cache though, 4mb doesn't cut it according to mike smith :) > Enterprise 1400 - > Cheaper than the mylex at $980, i960 at 66MHz, 3 channels, battery backup > for cache. > > Enterprise 1500 - > Similar to above, $1150, i960 at 100MHz, 4 channels, battery backup > included. > > So what have people chosen so far?
