The general rule with electronics is the cooler you run it, the longer it lasts. Of course you can get too cool. Resistors, capacitors and other components are generally rated at 20 degrees Celsius. So if you operate electrics at temperatures significantly below that you have the wrong resistance and capacity values. (The same applies to running too hot.) Also, at very cold temperatures frost build-up can be a problem. So I would not stick my NSLU2 in my freezer and expect it to work for long, but I would not hesitate to keep it in a cold room in my basement if I had the electric and internet connections there.
However, in the end I have had both my NSLU2's long enough that I consider them end of life. All my server functions are now running of my Asus RT-N16 and the NSLU2's simply are my backup servers.

Because of the black roof tiles, it reaches 45° degrees in the summertime. Sometimes also 45 in the winter, after the whole family took hot water for the bathtub =:-)

So I repaired the PSUs and moved my whole setup to a northeast windowed storage room in the ground floor. Now they are in an open IKEA cupboard, together with an APC power backup, at 15..21 degree Celsius. The room also contains our very energy efficient freezer. The NSLUs + Disks + UPS + switch + DSL modem are generating more heat then the freezer does, at least for my feeling. Since 9 or 10 month, the new place is running well and the NSLU2s never again got hot or shut down or such.
