While perhaps not the most straight forward character concept, I have always thought techno mages were really neat, especially that of a Chaos Mage (using tech even in magical rituals and such).
They both use similar attributes (mental), so it usually boils down to nuyen spent on hacker stuff (50k ish) and skills.
Using the Karma system (and only 700 karma despite the book saying 750), I made a very plausible hacker/mage. With the SR4 system, this is even easier, as essence does not need to be spent on implants. I bought them anyway (a math SPU for example) in my example, but for an archetype, that could probably be skipped.
So, to boil it down to archetype terms: A Techno Wizard, human mage focused on utility magic and hacking
