Yea, the 2012 build was a 3770k with 16 gb ram, multiple SSDs, a GTX680, etc. So it was a pretty fast machine back in the day.
I upgraded the video card and SSD drives several times, just didn't have the budget to replace it all at once for a long time.
I can't find it now, but I saw a video just yesterday of a lady with one hand chopping onions and some other items. She had an implement on the counter with pins facing upward that she could stick half an onion on while cutting it.
I'll keep and eye out for it, but in the meantime searching for "one handed cooking" on youtube will get you a ton of interesting things, from gadgets to methods of dealing with prep.
