I know people like to build their cab as cheap as possible, but when i built mine, I learned a few things, dont go cheap on the controls buy the good ones to start with. The same with the computer I purchased cheap parts, pcchips mb etc, & I payed for it, get the best computer for your buck, you wont regret it later, i did a 3000 amd 64+ with a gig of ram & it handles, most roms( & this system ran about $350.00) use a big hard drive the first time, i wanted to save money so i purchased a tv, I hated the picture then i purchased a arcade monitor...so i did everything twice, the moral is spend the extra first time its cheaper in the long run, sometime i will see post about people stating they really on a very tight budget, this hobby is not cheap its best to take your time & use quality parts etc
thanks
