Jopes has got it,and I do both jobs ,and I know positively computer repair ect .......... much easier.
Dust I take em out to shop and blow em out first thing,then start on repair.
Cuts from pc cards........ cant say as Ive ever got one of those ,I just take out the screw and pop it out.Hp's can be a bit cramp you just gota slide those drive bays out and walah,Ive seen idiots half put on heatsinks because they didnt know how to slide them out,lol.
Compaqs,some are quite redundant ,however most from the factory have inherant problems with drivers and such, and stupid compaq programs.Especially win ME compaqs ,big problems.
We have a Compaq out in the shop for 4.5 years 24/7 been running like a charm.
I have lots of different tools I use on computers ,I have a basic set of screwdrivers and pliers ect.$100 ,then for networking I have crimpers and testers ect.$100 there...,then at the shop I have my software I like to use ,also 1 computer dedicated to repair ,of harddrivers or for copying drives ect $200..Then I have a few stations setup to plug in computers ,so a few monitors and keyboards and mice and speakers ,maybe $600 there.
I have a few components for testing cpus ram ect.basicly mobos for AMD\Intel socket 7/A/370/slot1 then a pci vid card and a few other things so $200 there ,but not $1000's for computer repair.
Then laptops I have a few items like $300-$400 there ,lets see there was construction I did on the stations ect..but again not even 10% of what I have for automotive use.
1 set of sockets is like $120 ,specialty tools are astronomical ,and you dont use them alot either ,then wrenches and pliers good god Ive got like 40 pairs of different pliers the list goes on and on and on,very expensive tools.
