I have here an 80 gig hdd (maxtor) running in my qube2. First with the 
original powersupply, only that bugger burned itself up. Cruising around 
google it looks like that was a known issue. You can luckely replace it 
rather easy with a multi-use powersupply (can get those at any electronics 
shop for a fair price), you only need to make sure that the Volts match the 
original qube2 power supply, amps can be higher (gets you more Watts, so you 
can kick in some more hdd's).

Now it manages quite well, stays up 24/7 and works pretty nice.
