We need a server to host a open source project. I have looked at many different providers and have yet to find what I need (or find a company with what I need in stock)..

Specs:
Celeron Processor
512Meg Ram
40 or 80GB HD
Unmetered 5 or 10meg connection (i dont care if its cogent)
Price: It doesn't break the bank
Company: Needs to be reliable

Currently the project uses around 400GB of transfer per month, we don't anticipate it going over 1000GB-1500GB in the next 6-8 months but would like to get something in place so overage fee's are not a concern.

Any suggestions would be great. Thanks.
