The problem with building your own desktops is that it can end up messy and the built desktop looks absolutely ugly
not really, unless you're using secondhand parts. I have 45 minutes worth of battery power on my desktop.
prebuilt computers are still built by people you know. People who are trying to build as many as they can in as shorter time as possible, and trying to make them as generic as possible.
for 15 minutes. a gaming laptop has high-end hardware, and you're supposedly playing a game. that'll last you 30 minutes tops. i've tried it. i thought it too. but hey, the real problem is not building it, it's about getting the BIOS right, installing the OS and then correctly installing drivers for your components (and all of this is fairly easy).
if you're really worried about building it yourself, work out what specs/parts you want (we can help you with that), then take it to your local computer shop (not a chain such as PC world, but a small one staffed by a couple of local people). Stores like that will take your list and build it for you.
indeed, you'll just pay an extra (at least that's how it works back here). but it's the best way to go if don't feel at ease building it yourself.
The issue will be trusting them to put in your expensive components and not switching them for lower ones
@loony how did you get a 45mins on a desktop? i thought it was supposed to be plugged in an outlet? is there a portable battery that can run a desktop? would be useful in times of blackouts...
No, its a 1.5kVA UPS unit. basically a very high capacity battery. I have the top one (the tower). You can get UPS units from 300VA to about 10kVA (you can get higher ones, but they're either rackmount only or they need permanent installation) The bigger ones arent really portable, the 10kVA weighs 110KG (more than I weigh), and the one I have is about 21KG.
