I figured that, just in case if you "inherit" some money from one of your relative
, you would be better off going for consumer grade computing. I have this $20,000+ computer in my home, and while it is a beast and can handle everything with ease, but from a consumer stand point, it might be more efficient using a consumer grade computer for the speed and practicality. I require massive amount of RAM and this 20K+ fits the bill for me and it and has room left to install more RAM. The machine weighs roughly 100 bounds and does increase my electric bill by about 20-30% when using it. My next build will probably be consumer grade, that is if I can find a motherboard that supports the amount of RAM that I need, but then again it's not written in stone yet.
It seems like you're looking for something in the middle, budget friendly with some performance. Not shopping for a laptop, however the laptop posted on the first post, does seems to fit the bill. As someone pointed out to go with Clevo, as you can actually upgrade the component except the GPU, as that form factor would be very difficult to find (unless they changed it to use standard form factor) as you go, but it is up to you.
Over all you know what you will need and how much you want to spend. Just go with the one that you feel will meet your need, without breaking the bank, and don't look back. Everybody will have different opinions and that is good, but you're opinion matters the most, because you would be getting the laptop on your own dollars.
