If you wonder how you "mount" those brick units in an enclosure. Get some of 3M's latest industrial velcro and use that. The stuff is amazing. I buy it from Menards in the Midwest, USA." Scroll to the bottom of this page.. http://www.mini-box.com/Power-Supplies-Kits $35.00 If you can do this for less than $35, please tell me how. The 80 watt unit has more than enough to supply a D525MW system in normal temps. If operating in a hostile environments I go with the bigger power supplies just to keep the operating temps low. It is cheap insurance. Be aware that some of the bigger brick power supplies have a fan inside that goes on and off... I try to avoid those.
