Upgrade Of The Linux Computer

After building and running this computer a few months I decided it was time to upgrade it a bit. I obtained this motherboard from one of the liquidators for $20 last summer. It is an older socket 775 ATX board running a Celeron 3.33 processor with 4 GB of DDR ram.
Having developed a love for SSD/Flash drives, I installed a Compact Flash to Sata adapter board with an 8 GB Compact Flash card as the primary drive running Ubuntu version 9.04. There is a 100 GB hard drive installed for file storage.
I was totally impressed with the improvement in performance the compact Flash drive made. I have used Ubuntu on a number of computers but never realized the speed and response I have on this computer. This was an upgrade well worth doing considering the $6 cost of the Compact Flash adapter (bought on Ebay) and the $22 cost of the 8 GB compact Flash Card (bought at the local Microcenter).
Future plans for this computer are up in the air right now. It is a keeper. However it's full size tower case doesn't fit into the scheme of things in my home office/workshop. I've managed to have all the other computers built in small form factor cases or my computer cabinet. At some point I can see it taking up residence in the cabinet.
