The price alone set off a variety of alarms for me. Secondly, the machine itself seems rather outdated and disproportionate specification-wise, and "unlimited" monthly traffic transfer does not exist. I'd avoid purchasing this at all costs.
If it's too good to be true, like in that case, then it probably is. I agree with Chris, save yourself the headaches, and avoid that "deal".
Unlimited bandwidth does sound a little.. well, bad.. What company is this? Have you checked for reviews?
The word unlimited stinks of overselling, any promises of unlimited bandwidth should be completely avoided. No one can offer such services for that price. Unlimited databases is fair enough but certainly not diskspace or bandwidth, it is complete crap.
I cant find it on their site anywhere, tried the offers section and nothing the only one I find for 19.99 is their VPS and Premium shared packages, their lowest dedi seems to be 49.99.
Considering that some cellphones have more processing power than this server, you should probably pass this by.
The visual appearance and lack of organization alone would cause me to look elsewhere, as well. They're not exactly aiming for a 'professional' appearance - or, if they are, it's not being achieved.
