Thanks Muso

Yes, that seems to be my machine.

I have two usb ports, one is used for the mouse.

As mentioned earlier, I bought it about two years ago and I think it's about 5 years old.

I hope to get BIAB in the next few weeks, I hope there'll be some offers in time for Christmas. I'll be using headphones for monitoring.

I'll get back to you with the other information once I've purchased BIAB.
