Will This Work!?, will this setup work? Options

[lucky13]

Hey everyone just a little ..actually a lot of help needed. I want to start recording my band at home, have been considering a number of options and ive come up with this, bearing in mind im a student earning pittance and cant afford high end equipment. First up the 1.42 ghz mac mini. I really, REALLY want this as im going to be travelling a lot and dont have much space at home, it suits my needs/budget perfectly. So what kinda configuration of software and mixers would be appropriate for this? The band is a 5 piece death metal band (vocals, guitars, Bass, Drums and Keys) and we'd ideally like to all go through mic'd up amps rather than going directly into the computer..if you get what i mean :S I looked at the ALESIS MultiMix8 USB and reckon that if we plugged that into the USB of the mini mac and then plugged mics into the alesis ..hopefully we could record using garageband which is included with the mini mac. All the tracks would be done separately but we need the number of inputs on the mixer for the drums, cos its a bigarse kit n needs a fair few mics to sound good. Does this all sound like its got a cat in hells chance of working? is there anything that i might have missed? or have i got the wrong end of this whole recording malarkey!? help would be very much appreciated! thanks in advance.
