What HTPC do you use for Kodi?

I am looking to upgrade my HTPC from scratch – opting to buy a case, processor, motherboard and related hardware to run Kodi and mount in my home theater rack.

I’m curious what you all have done hardware-wise to get the most out of Kodi – from budget applications to high performance.

My current install is an Acer Aspire R3700. It’s “adequate”, but the image quality isn’t quite as good as it could be and every once in a while the image ‘hesitates’.

I’ll probably use the PC to stream (netflix, Amazon, Hulu …) as well.

Thanks!
