Yes. This is quite easily done.
Here is what you need to do:
For the frame: Grab some 80-20 bars, bolts, and connectors. That's the easiest way to build something like this. Alternatively, you can weld stuff, but welding Aluminum can't be done well with out a TIG. You can use steel, but that heavy. Here is the 80-20 stuff: http://www.8020.net/ Use 1/4"-1/2" Polycarb (pretty expensive but easier to cut/work with) or 1/4-1/2" glass for the top cover.
For the PC:
You need a PCIe x16 Flexible Riser Card, some thing like this: http://www.logicsupply.com/products/pelx16_c11
Obviously, you will probably want to go with water cooling, but it is possible to use a TRUE120, Mega,CCF120,etc if you make it deep enough.
Use cable sleeving. Otherwise it's going to look like cr@p.
Use quality parts for the PC (ie. no Diablotek PSU).
Keep enough space for future upgrades. Lay out the motherboard area to fit a EATX or bigger along with 2x big graphics cards (ie. 2x480s).
edit: If you are interested in modding, I highly recommend bit-tech. There are some really good modders there and a lot of people are willing to help you, not to mention they have some really useful guides. Link: http://forums.bit-tech.net/forumdisplay.php?f=88
