TranquilPC, unreliable ?

Well, it seems it is not a good week for my hardware.. Yesterday, my server (the tranquilPC one) was no longer responding and when I tested
it today, I discovered it no longer boots at all :(
I've revived my old Pentium 233 as webserver/gateway (damn, it is really noisy) and I'll contact TranquilPC directly to see if they have
an idea on the problem and after that, Mini-itx to see if I need to return it (which will mean paying to shipping from France to UK :(
