I'm lucky enough to work in a job that covers system building that actually pays very well and is actually interesting. (well ok for the job 30k+)
The company is a Telecoms Software house but job includes sourcing reliable / fast hardware dependant on application, building, testing, config and despatch. Along with that fault finding, in house server / pc maint, tech support to onsite engineer monkeys etc etc... on occasion the job also entails setting up LANs / Hotspots in hotels with crazy VLAN configs on stacked switches (which is a real PITA, but a challenge, set up one this week with over 500 VLANs

)
Also get to do the odd bit of coding in .net when the need arrises...
Perks of job... no management over us except company directors, work in own unit seperate from HQ and rest of staff, unlimited free home PC upgrades to test new systems long term.
Though building a PC can be done by anyone, building a well crafted / reliable rock solid system that must never fall over is another matter... but it's fun trying. I can hand on heart say I have never opened any PC and thought 'hey thats really nicely built' ...when we build them every system I send out the door I do so not caring if someone opened it up... they are that tidy.
I have no quals in computing, but basic quals in electronics, but that helps out when stripping laptops to fix...Anyway, not bragging rights, just saying that jobs do exist... they are just very rare but when you find them you stick with them, been at this place for 12 years
