There are a few things to watch out for when you are buying a box for home.
Firstly all when you are buying any POWER server, what licenses come with it? You'll need PowerVM licences to run VIO serversand get the benefit of virtualisation. You also need to make sure that the box is the right type, and can run AIX. Older POWER boxes may be limited to i5 or Linux. With a 570 you need to know what in the box has been licencesed, as some of the CPU and Memory may be turned off and be available as capacity on demand.
Secondly, if you are running virtualisation, are you happy to run a single VIO with IVM or do you also need to factor in an HMC. With the 570 you must use an HMC! The IVM isn't an option.
If you have an HMC and a server and want to run dual VIO Servers then you need a split backplane in you server, with disks attached to both backplanes.
Ago rack versus flat, the 520 and 550 come as rack mounted as well, but so long as the servers as kept flat is a suitable space then hey should be fine. You should also check on the Power draw of the server and what draw your household electrics will support. Just had a quick look at the 570 needs 200-240 volt AC power with is what you get as output on a racks Power Distribution Unit, the 520 and 550 should support 110 and 240 volt Power.
Hope that helps,
Ross
