I'll use a few months and I have tried to undermine the CPU of the PC but I would like to switch to external hardware you what do you recommend?
With the PC I tried to undermine litecoin because I can not even think of undermining Bitcoin because it is impossible
Thanks for your attention
That gear is for BTC uses sha-256 base software to mine.
It can also mine PPC with sha-256 . you will need a psu to mine with it.
It uses .77 watts per gh or around 400 watts on full power. It will not turn a profit unless you have free power and you can use the heat that it makes.
ebay seller of a psu

the s-3 on ebay

so the psu and 2 s-3's would be okay on it total of under 140
or the psu and 1 s-3 total of under 90
it will lose money with out free power
Thank you, How soon can I get a profit?
No one can say exactly for sure when you will hit profit. To many varibles such as seem's your looking at buying in USD. So BTC could raise in value during mining and hit quicker. Also we don't know what difficulty will do over next month's so we speculate. But we just don't have the info to do this even for you.
For a S3 you need very very cheap or "free" electricity at this point they are good machines just dated. What is your electricity rate? (include fee's and taxes)
