size tower? A bigger case is 99% better than a tiny case. No one said anything about triple GPU's. You can buy full case towers for more air room and potentially have the option to upgrade in the future if you ever want by adding more goodies. Smalll pc case, no chance. You can usually put a pc together with a phillips point screwdriver and time. Youtube/google is great for explaining how to do these things. The hardest part is making sure it all fits in the case, and the parts are compatible (both of which are done up the top). You could probably put this all together in half an afternoon. I'd spend longer routing all the cables. EDIT: once booted, connect to internet and update all service packs/fixes etc before installing update. If updates are failing, install them in groups of 5-10 between restarts. I have built a few and would take maybe an hour to put together, with no experience 2 at the outside most, it takes far longer to install all the software than to put it together. Allow 2 hours for build and 3 hours for software. Although if you go Windows 8 over Windows 7 this will be reduced as there's far less updates to install which take the most time in my experience. You could go an i7 for an extra $100 but would make no difference for gaming. If you were running all games off the ssd you could save some money
