I've had four of the things (I bought three other SN41G2V2s on ebay as a job lot that had been used as college machines). They've all failed for various reasons. I've managed to cobble together a single working example from the parts that are left from the three ebay boxes, so only two of them are now in working order. It's a shame because for their size, the boards are really well specced (built in IDE, graphics, firewire, USB, LAN, audio including optical in-out), and for their time, they're awesome little boxes.
I suspect the heat kills them - aside from the PSU fans (which are tiny), the only fan to cool the CPU and ventilate the case is a single 80mm at the back blowing air through a heat-pipe radiator. They've always ran hot, even with cooler processors.
The one that is the subject of this thread was a update (v3) and had built-in SATA and a GeForce MX. The replacement board I found on eBay for this unit has SATA, but no onboard graphics. Getting hold of a similar Socket A board is difficult now, they're hard to come by. It's the only reason I want to repair it, if it was the same older model board as the others (IDE only) I'd probably just bin it.
