I have a desktop PC, and well, I hate it

my bro has a similar in power laptop (we bought our PC at the same time), and he hates it
So we decided to swap our computer, so that everybody is more happy.
Biggest problem for me, is that I loose my M-audio sound card (wich is pain in the ass for me, acutally - for several reasons). My bro want's a 5.1 home cinema in his room, so he could use my audio card, with 8 outputs.
So I will be needing a multi-channel audio interface - more money spending

Anyways - I decided to go with
Motu Mk828kmII
It will be an upgrade for me, since it has guitar preamps with phantom power, mic preamps, 8 line analog ins, 1 digital in for my fantom (so I'll have 11 inputs, instead of 8 wich I have now).
It can also be used stand alone, without a PC - so you it is also a digital mixer.
So have anyone used Motu Audio interfaces? I have Motu MIDI interface - it feels like it's quality stuff.
Are there any other alternatives, in the same price range, with same features? (about 450 euro)
