Huh? What exactly does a email server have to do with files? Do you want this as a server to send and recv email - or a place to put and get files?
Either way - you sure and the h_ll do not need 2k3 anything to be able to setup a email and or ftp server, etc.. Sure if you have a trial - you could play with it. But as you stated - this is a "TRIAL", that does not mean you can use this forever. And according to the eula, you can not use it as production. I would think - using it as your email server, or ftp to get actual files you need/want for normall everyday use - is not in the spirit of "TRIAL" and or testing, etc..
What did you say the trial was for? 180 days - so what you get it up and running, like it! Are you then going to be willing to fork over the cash for either SBS, and or 2k3 server and Exchange? Not CHEAP

There are plenty of FREE, easy to use and configure email servers - that you could use. Once being Mercury mail, www.pmail.com - Tie this with a web interface, say squirrel mail, or horde, etc.. And hey - pretty slick setup.
I would highly recommend against actually attempting to use it for incoming or outgoing mail. For starters - is it even OK with AUP to run servers? Is smtp even open by your ISP. Quite a few actually block port 25 in an attempt to limit the amount of spam flowing out of their networks due to misconfigured machines, virus infected spam senders, etc.. If you on a dynamic IP, you could have issues with IP changes and people sending you mail, etc..
When you think about it - the cost of actually just leaving your "server" on for 24/7/365 (shoot for the cost of leaving on for 1 month - you could most likley pay for a full year of hosting and domain name) will cost you quite a bit more than what it would cost ot host the email on a server designed to do such a thing. If you are not happy with your ISP mail - there are plenty of FREE emails providers (gmail, hotmail, yahoo, all come to mind), or for like $40 a year could have your domain, and a webhost to host the email, along with file storage, etc.. etc..
As to providing personal access to your files on your home machine, network - hey I agree, this can come in very handy!! But again you do not need a full blown server OS, ie 2k3 to accomplish this. There are plenty of ftp server software packages available, quite a few for FREE, and not a limited to so many day trial, etc.. Cerberus and Serv-U come to mind, the list is quite LONG!!
Again you really need to check with your ISP, to ensure the running of any server is not against your AUP.
edit: as to your machine - yes that will run 2k3 without any issues. And can surely run ftp and or email without any issues.
