Replacing PSU on Ultra 10

[raymond.meyer%rambler.ru@localhost]

Hi, I use Ultra 10 as my main desktop system. It's sitting right next
to my desk and the PSU fan is a bit loud. I was thinking about getting
a quiet PC type PSU that has similar dimensions to Ultra 10's and
putting that in Ultra 10.

So, my first question would be does anyone know if this will work, i.e.
is there anything special about Ultra 10 PSU or is the same as other PC
PSUs?
