Make sure you have a business plan for short (build up), medium (diversify service), and long term (expand). Its good to dream about expanding, but keep it real and get there step by step. Your first goal is to stay above break even for the first couple of years, while building a customer base.
The glen's idea (on-site customer support) and the custom cases (I hope you meant customer designed - you-assisted) are good services to have. Service is where it is going to be in my opinion.
alright guys, I'll start off working with my friend's mom's business of Pc service (I'll open the Naples division in my mall, his mom has the Ft Meyers division.) It is called CSA which is Computer Service of America. Once I get some more moola I will start a separate thing that creates custom cases, and yes they can be customer designed or I can put up some examples that I'd do.
Like I would start my own PC service business but competing with my Best Friend since 1st grade (and his mom) is hard to do and they are already pretty well established. As I said I could just join and help expand which the money would help me expand my ideas of getting a CNC machine for making Wacky things.
I also just got the idea of maybe trying to swirl a pc case??!?!??! hmm??? Would it be possible? hah
Also with a CNC machine maybe I could make custom fan grills and custom metal window decals. Also maybe as an addon service to the typical virus remove, repair windows stuff maybe have a service where I can reduce noise of your PC (I know my PC is a beast for noise so I think its an alright Idea), because I have access to high quality acoustic foam from Yamaha since my dad's Piano Service business is sorta attached to them
One last thing, hah, from reading what you guys think I have definitly decided to drop primarily building pc's (maybe as a side note kinda think I could do) and I am trying to go for stuff that is not offered as often but would be pretty sweet to have. I know that ive seen only about 1 custom pc case maker and he sells them for A LOT!!!! so if I can keep coming up with cool ideas that I know the consumers will consume (duh) then I think I might have something. What do you think?
edit: WHAAA I just got another idea!! How bout selling Modded HD's that have like LED's and Clear Windows, If I do do that I would probably start with selling them and not modding current hd's that the person has already because there are chances of messing up the data. (I will practice with crappy old HD's first hah) and once I get good I can mod your current HD (and yes I am not dumb I will still back it all up)
double edit (lol) : on more Idea, I could solve temp issues with pc's as a repair service. I know sooooo many people that have had problems with their pc's because of crappy fans and stuff like that, I could use my knowledge of air flow and physics to create the best cooling for your PC. (maybe add some LED's here and there
) Also maybe have a thing where I could Window your non-windowed pc case
