I've got the Netgear switch at work, it seems to do the trick, it's got rack ears and withstood some numb nuts utility engineer sticking 600v up it in its previous job.

As for the NAS, i'd build a box to that, but if you don't want to do that, or let me help you cobble something together then the NSLU2 seems to get good reports and seems to be quite easily hackable.
