Running 20 currently, waiting for the rest of the hubs to come in.
Best hub for $/per port I found was Rosewill RHB-500 (10 port, 8 usable. $22 @newegg.com), I tried the D-Link 7-Port, only seemed like 5 were usable, I tried a few other hubs (got about $120 in hubs to return at the moment), so far the Rosewill RHB-500 has been the best. I plan on maxing trying to max it out on the one rPi to see how many I can get going just with one rPi with MinePeon.
Some pictures of my setup (not complete & dark, made from a NZXT Phantom case I had laying around), this setup is running MinePeon 0.2.3a (with some added stuff), still not done modifying the case, going to cutout a space for an lcd display on the side, remove the bay hard-drive bay (currently the rPi is sitting there, it will get moved to the back) to fit more hubs & fans, the PSU is getting switched out for one with less of a power draw (psu only controls the fans atm, it was all I had without ordering something).
- Raspberry Pi Model B
- ATXRasPi board (addon for rPi)
- Currently 3x Rosewill RHB-500 10-port hubs
- Currently 20x erupters
- Some erupters have heat-sinks, some do not.

Here's my test Pi, running raspbian w/4 erupters.
** Edit **I did forget to put in one thing, every time I try to use a USB Wifi and try to connect to it using 'sudo wicd-curses' it completely locks up I've tried it with the USB Wifi on a hub, on a hub replacing an erupter, on the 2nd USB port of the rPi, always fails. I want to try a different wireless manager for arch, but haven't got around to it yet, mainly because I have wireless-to-ethernet adapter (Trendnet TEW-647GA) which makes it still wireless, but wired to the rPi).
