Slink,
I opted not to go with the super-mini cases, but rather just a microATX which is about the depth of a mini-tower but only 9" high, and about twice as wide. So it's just a desktop case, essentially. The physical volume of the case is actually fairly large, and it has expansion for two hard drives (I already have three external USB2/Firewire drives), two 5.25" drives and a 3.5" bay in the front, two full-sized PCI slots, a PCI express, and a PCI Express x16 for a video card (which I'll also be adding).
I ordered one of these:

I'll probably set up a partition for SUSE Linux on the new system. I've gotten to really like KDE as I've been using it from a Linux Live CD while waiting for the new hard drive to ship (it probably won't be here until Friday).
It'll be nice to have a modern GPU though. The laptop is a 2-year old model now and the graphics card they put in it was a year or two old when it came out. It's only DirectX 7 compatible.
And I'm looking forward to being able to upgrade little by little like I did with my old desktop system back in 1997, which was the last time I didn't have a laptop.
I'll probably sell this one once it's repaired and buy something smaller to travel with. It's a monster system for a laptop but it's huge.
I'm very excited, though, and am hoping that I'm not wasting my money with a dual-core X2. The chip I ordered came in third or fourth in the extensive Tom's Hardware Guide benchmarks this year, and the only ones faster cost several hundred dollars more, so I think I made a good decision. The thing will of course be obsolete by the time I assemble it.
