Looks like I might have to ditch the whole kit, even though it all works and is in fantastic condition, I cant get a power supply for it. The PSU I have now has completely failed.
Just so anyone who is in this same boat as me, I even contacted Delta Electronics, with all the specs who actually make the PSU, and there response was that they cannot sell to individuals, there contracted only to named brands. Maplin, who I purchased the Scaleo E from, no longer sell the systems and "appolgise for any inconvienience".
So Im doomed it seems.
I think next time I buy a HTPC, I will ensure it can adopt a ATX or simular PSU.
