Number of disks and power supply/case is no problem, I use this case: http://usa.chenbro.com/corporatesite/products_01features.php?serno=43 with sata backplanes, works good. I use the 8 and 12 disk cases of chenbro very often, very good product. The problem is like I said the controller(s). >> Does anyone know there are controllers with more sata ports or is it >> wise to use (very expensive) real raid controllers in this case? >> > At all, in a production environment I would feel much more comfortable > with the external boxes.

It has to be a linux box for several reasons (one is my own curiosity). I've heard about SATA-II multipliers, anyone has used this before? It allows me to use 5 disks on one SATA-II port, so I can use 8x4 drives...
