Any ideas how much gpu acceleration would benefit programs like these? I know he said sketchup is a 3D model builder or something.
I do not know. See my next comment.
Also, hes using an AWFUL laptop...3gb RAM, newer celeron, 250-320gb hard drive, and really crappy onboard GPU.
Well then... if that's what he's otherwise using, then even dropping the CPU down to a dual core Core i3 would probably run circles around that notebook.
Soo...anyone have recommendations for individual parts and where to get them from? I quite like this idea. Would it be possible to add in a discrete gpu later (prolly w/ new psu)? Should I ask this in a separate thread.
The case and PSU I mentioned both would not have the power for a discrete graphics card. If you want to stay small yet have that possibility, here are some case suggestions:
Antec ISK 300-150 or ISK 310-150
These are the same case, with different fascia. They can hold two 2.5" drives and one slim (notebook) optical drive. They also have one
low profile slot and 150W should be enough for a quad core with a low profile graphics card. The case is fairly small, but is heavy because it uses thick steel.
Apex MI-008 or Apex MI-100 or Thermaltake Element Q
These are all the same case, just looks a bit different from the front like the two Antecs above. The PSU is mediocre at best, but the case can handle one 3.5" drive, a normal optical drive and a normal sized graphics card (albeit not more than around 9" long). The big selling point of these is the low cost and use of "normal-sized" desktop parts.
Silverstone SG05 or SG06
These can hold even bigger dual slot 9.5" graphics cards and have better quality power supplies, but start just over $100.
