Here's a thought...
Are you tired of encoding on your slow pc or just don't want to keep pushing it and have it tied up on encoding? Tired of waiting to upload it to your seedbox just to release?
How does remote encoding sound? Why not do it all through a remote desktop connection to your very own private windows box and feel at home?
Current most basic idea of specs and comparison:
Intel Xeon i7 W3520 2x 2.66 GHz (optional Turbo Boost Technology @ 2.93GHz)
1.20 TB SATA2
5 TB Monthly transfer (Download and OVH to OVH not counted)
Compared to my AMD Quad-Core Phenom II BE @ 3.2GHz, 8GB DDR3, it only falls 1-1.4 fps short, benchmarked with the same source, and encoding settings on a slow x264 encode.
