IBM vs Maxtor...pretty much a tossup in performance...so one should look at reliability and since the 75gxp problems (the line the 60gxp is replacing) and my experience with ibm and maxtor drives I would go Maxtor...
When I bought my case they gave me tons of screws and rails and everything, then my mobo came w/ ata100 cables, so like most ppl then need isn't there for that stuff...
since it is maxtor w/ same warranty the only satisfaction of retail should be the box to ship it in if you need to rma or resell it...otherwise you just paid more for some fancy artwork on a box, one 1.44fd, a 8 dollar or less cable and some screws worth 10 cents...
