Slim Devices’ gear just sounds lovely, I don’t know if it’s outdated, sorry.
Your PC probably does use less power, but then again you don’t likely run a 40% overclock on a chip with a TDP of 120W at stock, 4 Physical discs and a big graphics card. Having said that My 470 GTX has cooked itself to death and I’m now on a 70W Fire Pro, so I guess I’m down about 150W on max power usage.
CDRs with no paint over the foil degrade very quick, especially if you live by the sea [as I used to]. Ones with thick paint seem to survive longer.
Anyway – OP – check the Slim stuff out, they do sound magical and are pretty capable.
