Who even plays Crysis in an internet cafe? ...
Maybe that will be his unique selling proposition
("the worlds only internet cafe that offers you Crisis to play... if you want to")
If you are short on money at the start up it would be like gambling. a) shall I buy better/costier machines to be able to offer crisis? If they don't play crisis there is maybe more power for the future, but also more value loss of the machines in a short time b) shall I buy less powerful machines at lower prices, but not be able to offer crisis? Well the downside can be, that you will be reinvesting after 1-2 years, because the machines are to slow for the future or you see it like, if the price is already at a low baseline, than the loss of money when selling them for newer ones will be not that much.
Both cost something (a. costs much once; b. might costs less but at two times). You will also want to have in mind, when you invest, what you will loose for a) and what for b) if the visitors are coming, but they are not coming much because of a bad first impression OR if it doesn't work out anyway.
Hm, I don't know...
Consider price for getting them versus price for electricity bill (cheap machine with high power requirement might be only cheap at the beginning).
! about flash: all the workarounds do not help, if there is a site that tells you "you need flash 10.2 to visit this page" and the plugin that allows PowerPC Macs to tell the asking webpage that it is 10.2, though it is 10.1 does not work.
I have this plugin and I still can't watch short sport-video-summaries, because the site (sportschau.de) still says "you don't have 10.2 installed, so piss off!". I contacted the television channel that hosts this page (it is one of the two major German state television channels. They told me, if flash can't be used, the site should usually detect it and switch to html5 for smart-phones, which should work on an old PowerPC, too.
Well it does not and I still can't watch it.
Would you like to always run around and try to get it running and help the visitor find out, how he can watch the content as html5, if the site does not switch on its own? Most customers will just quit the browser and go away, without tellign you it did not work. After a few months you will think "why are less and less people coming?"
I do not think Romania is that much of a poor or even under developed country that people will think "ok, I can't do that, but at least I can read my emails here" or is it?
Well, young people might like your cafe, if they can play games there that are only sold to them, if they are over 18 and they are not, but letting them play these games at your cafe might be illegal, too. I do not know what laws you have over there. In western europe one would think that you can buy a copy of a game for cheap in Romania anyway, is that the same to residents of Romania, too? Or just a cliche.
Electricity again (measured it myself with a wattmeter):
- iMac G3 DV 400MHz uses about 100W, because of its built in CRT. What will an eMac with a bigger CRT consume, though with more CPU power?
- ibook G4 12" 1,33GHz uses about 30W, youtube-videos: cartoons at 320p are ok, only skipping frames/jumping, every 10minutes. Sports at 320p, stop-motion picture-show, with skipped scenes. 240p like looking through mist
- PowerMac G4 500MHz = 55W
- same PowerMac G4 with 1,2GHz (7455) Upgrade = 90W (almost same to the CRT-iMac)
- same PowerMac G4 with 2x1,8GHz (7447) Upgrade = 145W (youtube would not use the second core though)
I did not test web experience on the PowerMacs.
Now, what consumes an iMac G4, G5, Intel? I never had one. But using an Intel-Mac may be more power at the same electricity used.
Buy yourself a wattmeter. Buy some machines the other users recommend at EBay. Only buy one and sell it again, then buy the next. Do all tests on them that you want and make a note, what they consumed and how your experience was.
After doing these test, make your decision/calculation: buying price + electricity for number of hours the cafe will be open + fees for the room (if it isn't yours) + considering future reliability and value loss over time.
