If you are happy with Raspberry Pi or BeagleBone Black, they are the low cost 
low power way to go.  They run Linux.  They don't have a real disk.  If you 
do a lot of "disk" activity, you might wear out the SD card frequently enough 
to be annoying.  That hasn't been a problem for me but I don't have a lot of 
years on them yet.  You could use a USB disk.

The Raspberry Pi has a HDMI connector so you can run a real display.  The BBB 
has a mini/micro HDMI connector.  I ignore those and ssh in from my main PC.  
(Some people refer to that mode of operation as headless.)

You can get no-fan style power for Mini-ITX size systems.  The ones I'm 
familiar with have a tiny DC-DC converter that mounts on the big power 
connector and runs off a laptop size external supply.

You could just change the fan or whole power supply whenever the fan dies.  
Maybe you will get lucky and find one with a fan that lasts a long time.

You could try an old laptop.  The battery will decay over the years, but it 
will probably work well enough to cover short dropouts and/or let you wander 
around for a few minutes.  Some laptops have fans.  (I have a Dell Latitude 
D430.  It has been running 24x7 for several years.  The fan still works.  The 
battery is only good for 10 or 15 minutes.)

These are my opinions.  I hate spam.
