Scott, We have been using RT here for the past few years and our ticket load is close to what you describe above. We currently have just over 200k tickets in the system. We are currently on the initial hardware purchase 5 years ago of 2 Dell 2650's with a internal RAID controller to manage the disks. We purchased two to provide a redundant environment that would allow our ticket system to survive the failure of a complete box. On the assumption, that it will be hard to manage repairs to critical systems without an out-of-band trouble ticket tracking system to consolidate work. The web frontend runs on one of the boxes and the PostgreSQL DB runs on the other box. The DB is replicated to the frontend box and a copy of the frontend software is available on the DB backend to allow it to also serve as the frontend. The boxes each have 4GB of memory, 2 3.0GHz Xeon, 6 x 146GB SCSI + battery backed NVRAM cache. This system is currently running RT 3.4.5pre1 and PostgreSQL 8.3.5. We are currently preparing to upgrade to RT 3.8.x with a PostgreSQL 8.3.x backend on 2 similarly configured Dell 2950's. My comments about the hardware are that it is easily able to handle the number of requests that you need. I can not really tell you how little resources you can get away with using. Others have been using VM's to good effect. I would say that one of the major complaints that we have had concerned the ability to perform full-text searches within the attachments and large custom fields. I would recommend a backend DB that supports that functionality: Oracle and PostgreSQL. Good luck and I hope this helps.
