Looks very nifty with that i7 processor, however I'd recommend buying RAM from crucial and at least having 8GB if you want to effectively play MMORPG's ;) I take it you'll be installing the OS on the SSD, this will make it incredibly fast at doing tasks such as moving files and launching...
I would suggest a free webhost such as: http://www.000webhost.com. On there you will get ftp details which will allow you to quickly upload your DCR files via an FTP client such as FileZilla. If you don't know how to use FTP google it, or check the host for instructions.
