I'm using 2xNova T's and an Aver Media A800 USB thing. The A800 refused to 
work using the XP drivers when I tested it on my laptop, but it works 
perfectly under Linux! In fact I found the tuner to be better at locking 
to streams with low signal strength than the Hauppauge cards. (BBC HD 
trial from Crystal Palace)

I'm using a 3ware 9650 SATA raid controller, which works very well. Nice 
and fast.

I'm running on a Core 2 Duo 2.66G (cant rememebr the number now). This can 
transcode stuff for my ipod in 15mins for 1hours worth of video. This PC 
is also running Asterisk, and various other things like mail and samba for 
5 other PCs. All works great. I have the frontend on a different PC.
