SafeCom SAMR-4114 Modification

Not Acorn or RISC OS hardware but this is relevant.
I have been using a SafeCom SAMR-4114 ADSL Modem Router for a
few years now and has always been reliable. However, about 6
months ago it started to play up. Mainly it just wouldn't
through-put any data. It maintained the connection but the
internet became intermittant. I believe overheating is to blame.

So, in my first Mod, I took the thing apart, drilled 3 holes
in the lower front panel and fashioned out of cardboard a small
air duct to take air from these holes and have it flow over the
main CPU on the PCB. Next I hacked a large hole in the top of the
case and attatched a standard PC case fan, with a nice silver metal
grill taken from a old PC PSU screwed on top. The power leads were
soldered to the internal power supply input on the PCB. I fired up
the new configuration and without a cloud of smoke all appeared fine.

I have had this running like this for about 6 months now and it has
been totally reliable. So now my Linux PC and my Risc PC's can
access the net and talk to each other without problem

Update to the above
This Router eventually died and was replaced with a NETGEAR DG834
That has now been replaced with a BT Fibre Hub ( July 2018 )
