*gasp* I'm actually going to agree with terp06 on that. No harm of course in joining the PE club if you're an IT veteran but I think terp06 was commenting on the short- to medium-term viability of making such a transition.
Despite the fact that a lot of MBA applicants are career changers, switching over to PE/HF/VC or even IB without any kind of prior background in that field is absolutely challenging, as is accomplishing the opposite.
In fact, I was recently speaking to an alumnus who's a Director at a bulge bracket in New York and he was explaining how hard it is for a former banker pursuing an MBA to try and get hired from IB to retail. Recruiting activities begin in earnest within a few months of you starting your first year in b-school and to try and make the argument that you've spent 4 years building models and preparing pitchbooks and now suddenly want to check out a summer internship that focuses on CPG marketing sounds a little weak. If you try to make the argument that you've worked in retail for 4 years and now want to do IB, it's even weaker, I suppose.
Obviously people do end up switching careers - rhyme moved from MC to VC I believe, and pelihu from law to IB - but IIRC they both had significant and somewhat related experience earlier.
I think if you look at it very objectively, the "MBA to facilitate career change" argument actually probably makes you somewhat of a risk in the eyes of the admissions committee, especially if you're talking about transitioning from IT to PE.

It's simply not realistic. PE firms almost exclusively take people who have previous PE or Investment Banking experience. They may take a handful of M/B/B consultants, but that's about it. If someone from IT is interested in breaking into PE in the long-run, they would be wise to get into investment banking in the short-term right after school and make the transition later. Although I see nothing wrong with joining the club, and finding out more about it, I think it is sort of over-the-top to put your resume in the PE resume book as it is premature for an IT person to be searching for PE opportunities.
