The PSU is not known for failing, and thus I would not worry unduly about it.
If you do have concerns, bide your time and pick up a spare locally when the opportunity arises. LCs and LC parts are plentiful (heck, I could sell you several), and even shipping for one of those little PSUs, or indeed the whole machine, would be cheap.
The LC475 is a great little machine. You will, however, need to deal with more heat in the case with the full 040 installed. A heatsink or an inverted casefan (drawing air up rather than pushing air out) might be worth experimenting with in this connection.
