@Lengo Removable motherboard tray is nice if you're planning to replace your motherboard every one to 3 months. Besides, a motherboard does not have a time bomb, aka an expiration date of 3 years. Maybe 5+? In that case, it helps to keep a motherboard in times of financial crisis. For a monitor, it's a personal choice, but I currently have a 50" 50PK950 HDTV from LG.
And yeah, I've already done my own partitioning by myself, as I have a 4.7GB partition for a page file, an 87.3 GB Windows partition, logical partitions for Kubuntu with KXStudio, and a 530GB partiton for storage. So yes, all of that partitioning is already covered. :)
Of course, I already have my server (running Ubuntu Server 10.04) for backup, but my server is not only a file server, but a router, a phone system (Asterisk PBX), MythTV as a backend, and a kernel-based virtual machine, since my VM runs Windows Server 2008 R2 as a home automation server and a web server using IIS 7 and ASP.net 4.0. My server is outfitted with an Hauppage HVR-1250 (Linux compatible), a wireless network adapter (ath5k, which I'm planning to replace that with a PCI wireless adapter with ath9k, if I can find one), and a PCI network interface controller. I have the two network adapters (wireless and wired) bridged together and I use hostapd for turning a wireless adapter into an access point.
I'm planning to get a 3TB hard drive for my server as both of my server and desktop have a 750GB hard drive, as I'm planning to move all my ripped DVD movies and all my user data to 3TB hard drive in my server. I'm planning to keep my 750GB hard drive for both of them as to not have an operating system be in the larger hard drive. It'd be nice to watch DVD movies in my internal network.
