There's no money in it.
Don't do it:
1) People will want an illegal Windows.
2) People seem think that as you built them a computer then EVERY SINGLE TIME EVER that it goes wrong YOU can be called over to fix it, for free!
Honestly, if it BSOD 12 months after you built it, they will ring you up saying wtf.
spie seem's to do quite well from it.
Fixed.you may as well set up a business where you pay people a fiver to kick you in the nuts.
The money is in the support not the hardware unless you are selling lots like ocuk.
You will also find you are competing with people who put pirated windows and office on for free, and so to the end user who does not care, is significantly cheaper then you! .... "being legit" means nothing to the majority of people it its going to cost them 170+ quid for windows and office.
Stick an ad in the local paper to do support, go out to people's houses and charge a fixed hourly rate.
My g/f's brother does this and makes a respectable wage from doing so, he's got a good client base and covers everything from new installs of store bought PCs, builds, upgrades, home theatre setups, networking etc.. Something you should be more than capable of doing too if you're building PCs.
This way you get to supply based on requirements, and configure/install without the hassle of being solely responsible for the hardware. i.e the onus is on the vendor to provide that.
you only need windows openoffice if free
I'd love to take on my local pc store, it's not a huge place, they have no stock 90% of the time but the two guys seem to be kept pretty busy. They're also completely useless and sell machines as new with second hand parts in and dodgy windows licences (they also sell linux CDs/installs claiming it to be 100% windows compatible when it's kubuntu with a windows vista skin on).
They still get plenty of business though, I already get about and do local repairs (mostly on machines they've sold) so I reckon it's something I can edge into on the side, still feel it will be akin to slamming my nuts in a drawer though.

And once trading standards come and investigate them for selling dodgy windows they will be gone, no competition eh *wink*
