Yeah , professional dreamer, i saw your little desk , chair and vintage keyboard lol. Like i said little toys for little boys and girls ...
Oh yeah you have a toy computer for single use with zero expansion path. You can always buy another little computer but you're stuck with whatever is on the MOB. Like I said there are draw backs to SFF and more with USFF. It's not the best choice for professional use. No upgrade path. Becarefull with recommendations on this blog. They will share their only experience.
FYI - PCIE come out before you were born in 2004. In the late 80's after i graduated we were getting $100/hr plus expenses for cobol, assembler, cics, db2 programming. They're still running in the major financial institutions
I trade all day and all night . I use a common DELL 3.2 GHZ with 16 gb ram...I get some freeze up on my charts on rare occasions but otherwise its ok. Cost was 1000 bucks canadian. My computer is on 24 days per week..or hours or months ..I lose track.
Buy any brand which will make you happy, I recommend to buy something from ASUS, simply I never had any real problems with it and that's really it. It's not much to do with price simply it's best of Chinese global brands for PC and laptops.
