As Sithis said, don't home host your server, there are pros and cons about it:

Pros:
*Easier control of your own server.
*It's free 90% of the time

Cons:
*Your PC has to be turned on all the time. (even if you have another PC you will be running it on, it will still take your house electricity, and make the bills bigger, cuz your pc has to be on all the time.)
*Slower connection
*The server may run slower.
*If you're unlucky, your internet provider may charge you more for hosting a server, over VPS and those things...

CONCLUSION:
What I'd prefer is, you should find a SA:MP hosting site, pay a bit of cash for it (I've seen good hosting websites, where you can host a server for 10-20 dollars, it's really cool), upload your server files, run the server, and that's it.
Pros: Better connection (if it's a good host), no need for your PC to be on all the time, no changes done to your internet upload/download speed.
Cons: You need to pay more for a special IP (ex. usually the host gives like: samp-rocks."servername".com:7805... and to have like samp."servername".com:7777 you need to pay more money).

Hope it helps.
