Hi all, I've been on a 4 year hiatus; and am just recently getting back into bitcoin mining.  I bought my first bitcoins via a WesternUnion 6-day process, while waiting on my ATI Radeon GPUs, 3 of them... looking at an old post, I was happy to be getting 160 Mhash.  Anywho, that system was a tower, with a board and slots to accomodate the Radeon GPUs (duals), and I'm just curious if the same chassis will support this 'AntMiner S5'?  Also, can someone point me to any of the 'recent' best mining practices.  As I know HW technology doubles every 18 months, I'm sure my old rig is well outdated - so, if there's a new way of doing things, I'm all ears.

Thanks,
CRYPT
