The balance between expandability and size is important for me. I can't fit the bigger case where I want to put the server - also like the look of the Mini P180

.
I think that I should be able to mount two 2.5 drives in the top area of the case using a suspension technique and by placing some spacers between the two drives to create a gap for air.
This will leave me with the 5 drive spaces in the main area and I should be able to again suspend two drives in the bottom of the case if ever needed. That makes a total of 7 possible drives = 6 X 1.5 = 9 TB (roughly with Raid 5) Surely that is enough storage

. I am currently only using 68% of my current 4 X 1.5 TB NAS. I suppose the real dilemma here is price -v- performance. The 1TB WD drives do use less power than their larger siblings but the 1.5 TB is the sweeter spot for buying while the 2 TB is just out of it price wise, though it uses the same power as the 1.5 TB.
I have settled on a Thermalright HR-01 Plus for my CPU cooling. Run passively.
I am still not sure on the motherboard. The Gigabyte GA-MA74GM-S2 has been rated here as one of the most power efficient systems when used with the AMD 4850e processor - but the Foxconn A7GM-S-2.0 still is appealing. I can always use it in a HTPC in the future if need be.
No this is about noise so the Gigabyte should be the choice as it will use less power hence less noise (I think).
I got a real shock yesterday when I put the power meter across my server and NAS Units. Pulling a consistent 202 watts. And that is with the hard drives powered down in both NAS units. I started this project due to noise but it may have some financial benefits in the long term. I wonder what my Fax machine pulls while sitting idle?
So my new questions
Does anyone have any figures on the Foxconn A7GM-S-2.0?
Will I need additional fans in the Mini P180 to deal with 5 hard drives in the drive cages?
Are the drive cages in the Mini P180 sufficient to quieten the WD Green drives or is there a better mounting solution out there?
All the best
