RE: BTC mining is back to profitability?

I actually think the 'build-your-own' PC times are back with a vengeance due to the popularity of gaming on PCs in the last few years. Back in the day, gaming on a PC was clunky and messy and the gameplay was never as good as on a console.
That's all changed these days and as I wander the local IT mall, there is a huge range of specialist gaming component shops, combining building PCS to a customer spec/budget (like in the old days!) and selling individual components for DIY upgrades.

Apple 2c....impressive as I have never actually seen one in the flesh! And like buses, you wait 20 years then see 2 in one shot!
